VHL, what is it that has been grinding your gears lately? I will start
1) When you are on a two lane highway with pretty heavy traffic so everyone is going like 20 or 30 mph. You are in the left lane and the car behind you is riding your ass because you are actually giving a normal following distance to the car in front of you. They believe that riding your ass will make the 100 cars in front of you go faster. They then proceed to switch lanes, cut really fast in between just to pass you, but are still stuck in that same traffic. Well done.
2) The other day on my drive to work I figured there must be an accident or something, because there was a 10 minute ish delay in traffic. It turns out there was no accident, merely a car pulled over on the side of the road with a flat tire or something. Because people are idiots, everyone had to look at this exciting event going on in the shoulder and slow down, causing this unnecessary traffic jam.
3) People who are rude to waiters,waitresses, or customer service for something that is entirely not that fault. I think it is important for everyone to work at least one customer service or retail kind of job in their life just to know what it is like. Often times they are just a cog in the machine of a company with really shitty policy. It is not their fault if they are merely following the rules assigned by their job in not giving you a discount or whatever. As long as they are polite (99% are fine) I usually am quite friendly with them, and shockingly friendliness can get you much further than being rude a lot of the time.
