Depending on which retail service you work for try going to HR or even outside the actual store (my company has a phone number outside our store if you aren't comfortable speaking within). In the company I work for religion is to be kept out of the workplace. Food for thought especially if you need to keep your job - if not, hail satan sounds good.

If he/she is saying it directly to you then, try speaking him/her in private. Or, add "or for us not religious, have a great day" my e, they'll take the hint.

It seems the use of "blessed", "blessings", etc., has come into vogue as a warm greeting, and not necessarily that of a religious nature. It is viewed as particularly non-specific to any line of thought and, thus, hoped to be easily received without offense.
Always best to assume good intent unless, as others have offered, you would not be inconvenienced by losing your job for snapping back with a verbally aggressive retort specific to certain beliefs. Oh, yes, that would be accepted by H.R..

Best wishes on your new job search.

turn it around and joke back saying "under his eye"

This made me smile.

There is a tradition in our family, that developed from one of our ancient grandmothers.
As a child, she got pulled up for the use of profanity in vexing situations.
Her mother told her, that whenever she needed to swear, to just say "Bless You", or "Bless them"

So now, when we hear someone in on the joke say "Bless You", or comment on a group of people and say "Bless Them", we know what they REALLY think.

My recommendation is to answer with a phrase that conveys your discomfort, by putting them in an uncomfortable condition without being insulting.

I might be tempted with something really flowery like
"And a blessing upon your ancient ancestors and their distinguished progeny", followed up by a deep bow and a flourish of the hand.

No the perfect solution, but you might try Blessed Be. Witches use it as a friendly parting comment. So, if the manager turns red, green, or purple you’ll know they are onto the saying. If they don’t turn some strange color, then you’ll get confirmation that that are clueless.

In order to retain our sanity in the face of of this type of mindless drivel we are sometimes driven to verbal retaliation. I use a simular tactic against those who cannot formulate a sentence without persistently saying ''You know''. Every time they say it I respond with ''I know''. In an amazingly short time you can see the brain engage and an effort to think about what they are saying is evident. So well done you.

I wish everyone who commented or even viewed your post would check this.

I hate it when store clerks do it. I probably look a bit maniacal.

But I've yet to find the appropriate response. It's their delusion after all and they're trying to be nice.

It was the National Day of Prayer the other day to which news I said "Hail Harry Potter". I'm getting jaded as I age perhaps?

I'm not sure what the answer is here - but good luck to you.

I usually respond with "have a good day yourself" if their aware enough, they'll figure it out.

No, not a good idea. Take the person aside and suggest something else.

I have to agree with a lot of other people commenting: not a good idea. Just let it go, it is about as inconsequential as something can possibly get.

I've had the people who work at Five Guys say that to me. I just blow it off. Sometimes I wonder if the expression means to go fuck myself.

Ask him if he's seen The Handmaid's Tale.

First, my sympathies for working retail, a thankless task. As for the Have a blessed day, watch out for the crap list jobs that you can be assigned. Worked for a christo-fascist at a big box store, unless you were a fellow believer you got the crap times to work including the open on Sunday and open on Monday!

I’ve noticed religious dog whistles a lot more lately. I guess I’m more sensitive or annoyed by it now. But I just shrug it off. A couple weeks ago, I was asked to pray after a game. LOL So awkward.

It irritates me as well... mostly because I don't like being told to do anything...no thanks, I prefer to have a shitty day...ugh

That phrase is exceeding condescending

Irritating

just blow it off...

good idea - piss off the guy that decides how your day will go - and probably what you get paid. Ignore the man or respond as Dave Allen (irish comedian) - may your god go with you - and one day it will

One of the meanings is for blessings = good fortune, so why not just take it as another version of: Have a nice day?

I think that people who offer such a salutation do so with a positive attitude, and do not realize that to a non-religious person is it somewhat offensive. I do not like it when someone says that to me, but I take it in the spirirt in which it is intended. I might smile, or I might simply ignore it. I try to not let it upset me, and I would certainly not want to engage horns with someone who might have the power to make the job either miserable or disappear!

I would say that's an appropriate response.. if you believe in satan. I prefer less friction in the work place. If they try to make it more personal then bring it ti her superiors attention if you feel you need to respond to her say something innocuous like don't "get run over" ..i prefer humor I guess.
