I'm a mailman. When I'm out on my route, people frequently ask for directions. Some of them pull over to the curb near the sidewalk while I'm right there, so I cautiously talk to them. Others yell "Excuse me" from their cars while I'm across a yard. I keep following my path and ignore them. I've had them get out of their cars to yell at me for not stopping doing my job and walking over to them in their air conditioned cars. They also get upset because I don't know my way around the entire city of San Jose, Ca.
