1. Traffic. A light turns red and 6 cars go through. The person in front of you stops to let a car in traffic and that person is waiting for a right turn on red! Training people. I do a lot training on my job and it really angers me when a person still acts like they don't know what they are doing after a month! Getting a slap on the but, even though it was in fun, watch out! You just might get hit back, sorry! It's a natural reflex for me.
