Please remove whatever is in your butt.

I know you may find it hard to believe, but I am yet again writing about rude people. I just don't understand. At my job, it never ceases to amaze me how many people manage to make it through an entire check out without saying one word to me. I tend to ask things like, are ya ready? did you find everything ok? your total is ____, thank you, have a great evening! and other junk that you say. Crafty rude people find some way to respond with a series of nods while staring only at the screen and refusing to make eye contact, or God forbid, actually smile. I'm not expecting a full on conversation (though those people can be a bit much also), but have some respect and don't treat me like I'm a computer or something. On another note, I think every single person who is having a bad day insists on shopping at my workplace that day. I swear it. Then tend to scream at me when I greet them or ask to sign up for a charge (yes I know it's annoying, and yes I know you don't need one, but it's my job, and I don't scream at you for trying to do yours). So I suggest the next time someone asks you for one of those crazy things, you just reply that you already have one.
So the next time you go to McDonalds, Walmart, or wherever and you just aren't feeling like smiling that day, force your grumpy face to do it anyway. It really makes a difference to them. I know you remember working jobs like this...
