Do you charge people who you give car rides to? My coworker needs a lift this Friday after work so he can catch a bus to his home town. I really don't mind spending the time to do it, but it's a lot of extra driving. It's a 30 minute drive in the opposite direction of home, and puts me in terrible rush hour traffic on my way home (I normally never hit rush hour traffic); it'll add probably 1 hour to my commute after I drop him off. I'm struggling with money at the moment and with my gas guzzler car, this will suck for me as I already spend about $10 on gas a day. Would it be rude for me to ask him to pay for gas? How much is reasonable to ask for?
