When I commuted in DC, I ran a little charity on the commuter train. The way it worked, you could only ride-share on the Amtrak if you had a monthly pass or a 10 ride ticket ($80). By the time you got on the train and found out you could not be on with a single you had 1 minute to go in and pay for a 10 ride and a step-up (that takes at least 3 if there is no line). If they didn't get off, it cost $300 to buy an Amtrak on the spot to avoid the $500 ticket. It was a particularly big deal because this diesel train was the last one into DC in the morning from that area.
My solution to this problem was, I carried an extra 10 ride in addition to my monthly (that my work paid for) and if someone had this problem, the conductor came and got me. (I was always on that last train). Well, one day a guy who was obviously gay hopped on and started asking one of the conductors if the train would be stopping in DC (obviously it would he could see commuters getting on). It was clear he did not know the routine. For some reason, I was not as eager to help this guy out as I had been a pretty mom with 3 cute kids the week before. I didn't have anything against the guy, I just knew he'd want to sit and talk with me and didn't feel like talking to a random gay guy. My conscience would not let me ignore the guy so I squared him away, and my worst fears were realized, he wanted to talk to me during the ride. Turned out he was a manager at a CVS. I'm sure glad I didn't abandon they guy, he would have missed a lot of work, and it would not have been very Christ-like of me.
