-Go the speed limit, preferably the speed of traffic. In the same vein, don't drive 25 mph in a 40 zone just because your turn is in a block or two.
-Don't merge in front of someone going 10 mph slower, it's effing annoying, and it's dangerous.
-Please, be careful when you turn right on a red light. I've nearly gotten hit many times both as a pedestrian and a driver with the right-of-way.
-If I see you coming up behind me, I'll do my best to get out of your way, but if you tailgate me, I WILL go slower just to piss you off.
-For god's sake, always look for pedestrians when you approach an intersection or a driveway. I'm sick and tired of nearly getting killed.
-Don't arrive at a store just a little before closing and spend an hour or two browsing. As someone who has worked 8-hour days in retail, I can tell you, the employees just want to go home. They're tired and their feet are sore from standing all day, and they absolutely hate you for keeping them on their feet at work for another hour past the end of their shift.
-Don't arrive at a place of business after they close and demand that they open just for you. Employees are leaving, and the registers are already down. It would take more work than it's worth to start everything back up again just to try to please an ungrateful customer.
-DoggieTown customers specifically: I have had no training in the front office and I cannot release your dog to you after closing, no matter how many times you ask. Please don't make up stories about how the girl in the office didn't correct you when you said you'd pick up your dog at 6pm when we close at 5. If you're a regular customer, you know the hours. If you're going to be late, call and we'll do our best to accommodate you.
-If an employee goes out of their way to help you or does an especially good job, feel free to offer a tip. It really makes their day. Just a few dollars is often like another half hour of work. Bare minimum, say thank you. It makes them feel appreciated even if it's only courtesy.
-Get the stick out of your collective ass.
-Do your damn jobs.
