Customer service point of view.
I have worked various public facing jobs over the years and I think it's a point of view everyone could benefit from hearing, so here goes.
There is a troubling attitude toward customer service workers that is so ingrained and pervasive that people become offended when you point it out. We are often treated as servants. "The customer is always right" has morphed into systemic abuse of clerks, waitresses and service staff in general. People will do and say the most awful things to them,knowing they'll get away with it because the service industry is fanatic about not offending customers.
I have witnessed workers being sexually harrased and stalked, physically accosted, threatened and assaulted by out of control customers and management. Even those who don't cross that line often fail to treat customer service people with any respect. It's not ok to be horrible to people because you don't like the prices,procedures or anything else about a business. The people you see and talk to DO NOT MAKE policy. They're just the sad sacks who have to put up with your tantrums over it.
Something many people may not know is that the service industry has been on a massive labor cost cutting rampage in the last decade. Most people can't get full time but are expected to have completely open availability at a low wage. Good luck getting a 2nd job to pay rent. Corporations don't mind turnover and even encourage it because it keeps them from having to give out raises, pay for benefits etc.
So that customer service worker who doesn't seem to care enough about whether or not the bread you want is in stock most likely is living on the edge of poverty, has no healthcare, next to no job security and knows very well that he could be fired at any time for any little thing.
Getting sick is a big one. People get fired for calling in sick all the time. You want to know why that bakery employee is working despite barely being able to stand? Because sick leave in most cases is draconian. You only get a handful of days, that are often tied in with vacation and family leave. Many places require a doctor's note if you call in for 3 consecutive days. Good luck with that when you're broke and don't have any healthcare, or an enourmous deductible that has to be met. So you can thank the service industry for the frequency of colds and flu.
In conclusion folks, customer service workers are broke,most likely sick, struggling with all sorts of financial and emotional problems resulting directly from basically being slave labor and generally despised by the public and their employers. So maybe try not to be such dicks. Also support your local labor movement.
