Three things following a failed trip to WalMart.
1) To the checkout manager, and I know you're the manager because it said so on your shirt, and the two cashiers on duty kept coming up to you trying to resolve issues with the people waiting for them. You have better things to do with your time than shuffle listlessly around the candy racks, checking prices and avoiding eye contact, while four families worth of people attempt to purchase a week's worth of groceries at 3:30AM.
When I approach the check out area with four items, and am stymied by this crowd already waiting and going nowhere, do the job you were fucking hired to do, and open up another register. I've come to understand that WalMart has some kind of policy against having more than one-and-a-half registers open during stocking hours (as part of their ongoing commitment against convenience); rules were meant to be broken. Help me out. Cut me some slack. Open a third register, for the people with cartloads of stuff if not for me. And if you're not going to, don't act too surprised when I dump my four items on the nearest shelf and leave.
2) To the cashiers: stay at your fucking register. Do not wander off mid checkout to talk to other people or help direct other customers around the store. You are busy, and you have the power to say you are busy. If you don't want to be busy, and no one does, resolve the customers already waiting for you. And if a customer wishes to dispute the price of an item, make one attempt to resolve the matter correctly - if it fails, concede. It's not worth your time or the customer's or WalMart's to try to talk these people out of any difference smaller than 50%. Hell, if they're going to be that adamant about the correct price on a pack of Bic pens, I'll make up the quarter difference myself if it will get them out of the store faster.
And 3), a sadly special and specific note to the people in line: Nobody likes stereotypes, but what exactly is a stereotype? An assumption based on prior information; pattern recognition, if you will. And it is beyond the power of my human brain to not recognize patterns. What I'm saying is that stereotypes come from somewhere, and there wouldn't be hurtful stereotypes in the world if there wasn't a non-insignificant number of people in any given category living their lives in unconscious celebration of them.
I don't want to be a racist; I would really appreciate it if some unignorable circumstances of the world would stop trying to convert me.
