I forgot my bite plate last night and woke up with a clenched jaw and a blinding headache, halfway to a migraine.

To make things more interesting, I had to go to the pharmacy when I got to work. They've given me a personal representative, so the entering of refills is painless, and in return I've decided to try and pick up my scrips before I go to my office. It's a compromise on both our parts.

But the service quality was its usual abysmal self. The snotty clerk behind the glass refused to make eye contact with me at any point in our transaction. This included handing forms back and forth, asking for a pen, turning in new prescriptions and taking the drugs that were ready. I was there for at least ten minutes. Not once, not even for a nanosecond, did the bitch make eye contact. She spoke at me, or in my general direction, but she never looked at me.

This sort of thing just drives me wild. I'm a freaking customer. Take my money, look me in the eye and say Thank you.

And that goes for customers, too. Put the fucking cell phone down for a minute, look at the clerk and make your request. Do not point or wave vaguely at something and expect the clerk to know what you want or mean. Do not keep yapping about your inane and inconsequential crap to the invisible person at the other end of the line. Put the phone down. Be polite. It won't kill you to be polite to the worker bees of the world.

Can you break your teeth from grinding them too hard?
