Here's a pet peeve from when I ran on the road a lot. I'd be running along, minding my own business, possibly setting a new personal best record for my run, battling the elements, fatigue, dehydration, heat stroke, etc., and people would roll up to me in a car and expect me to stop what I was doing and give them directions to QukTrip or whatever.
I would just keep running and ignore them unless they were going my way, then I would talk if they rolled along next to me. I would just tell them I was not familiar with the area and didn't know.
Some people would get mad, thinking my sole purpose for being out there was to give them directions.
