Namaste.

Live in Joy!!

In London we say Ta! its extremely short for thank-you and allows you more time to escape without mismaking yourself

I just take it as it is (in my opinion) meant -- to be nice. Their beliefs, being kind. No more.

Does it upset you?

May the blessings of the universe follow you for ever!

[etymonline.com] Thank you but I've already sprinkled blood on my pagan altar

I’m in Mississippi so I get it all the time sometimes I say nothing like in long lines .. but if I have time while I’m gathering my purse or whatever,..
I normally tell them, “try have a nice day cause we’re not all Christians.”
sometimes I say “Santa clause to you too.”
But if it’s a cashier I’ve already politely told I’m not Christian and they say , but god loves you anyway.
I normally respond with “all hail Satan”
Not that I believe in a xtian form of Satan at all, but Satan as a symbol for rebellious people.. and for shock value..

Each case is different.. if it’s an old person I just smile ..
feel it out and have fun..
Other things I say in return are ;
“the force be with you.”
“ have a magical day”
“By Odins beard you too.”
“Seven blessings “(GOT)
“Doesn’t compute”
“ pixi dust”
“Tardis appreciation day”

Anything odd back..

My response to all such similar well-wishers is, "Thanks, I'm workin' on it!"
But I also like, "May the Force be with you".

It always shocks the crap out of me. lol I was in my 50s before I had a store clerk in New England say 'have a blessed day' - I just stared like 'what now?'... I was stumped.

I do like the return blessings someone listed below though... I mean why not? And 'The Force be with You' just can't ever be offensive right?

I need condoms

you: "Blessed by whom?"
her: "By God of course!" (Assuming the Christian god.)
you: "Ah... vanity. That breaks a commandment."

The implied statement actually is along the lines of "may God bless you." The thing is that there's no reason to say this to the person one is wishing God's blessings upon, as it is essentially a prayer. It is done purely for vanity's sake, i.e. taking the Lord's name in vain.

I can tell the difference between a Christian just trying to be nice vs one being petty. I would like a snappy comeback for when someone tells me “I’ll pray for you” when they do not agree with an opinion I have. They will end an argument with me by saying “we’ll have a blessed day” or “I’ll pray for you” or something that indicates I need saving. That in my opinion deserves a snarky rebuttal.

I feel the southern obliviousness to their offensive rhetoric on a daily basis here in Oklahoma as well. What I tend to do is respond with is Salaam Alakum. It basically means and peace to you. Which mirrors their intended sentiment. And is the good vibes I try to embrace as much as I can. Yet also pokes at the fact that THEY do not appreciate even good will from other religions. So why must they persist in shoving their delusions onto me?

“Have a blessed day” is definitely a put down. Whether the holier than thou, poorly educated, christo-fascist recognizes this or not. It assumes a great deal and hijacks the societal secularism of “Have a pleasant, nice, great, wonderful, etc day” by appropriating your day into their kook religion.
This point is easily proven by them being placed on the receiving end of a Satanist cheerfully waving them goodbye while saying “Have a sacrificial day!”. How could they possibly take offense? (Especially when their manual is full of witches, ghosts, demons, and plenty of sacrifices ordered by their god).
