If they want money, no. If they want a specific favor, then maybe. A guy offered to show me specifically how to get to Hunter AFB if he came along. I obliged, but he wanted some money for breakfast at McD's before the gate. I obliged and thanked him. Especially since he saluted me when I was in uniform but only wearing a PFC rank. Now I know what officers get off on. Still I admire his ability to get a few bucks.
I gave a couple bums a ride back to their home in tent city. Funny mudderfukkers. Wreaked of rum, when I dropped him off by the utility box in the parking lot, his wife came out of the bushes and started yelling at him. He told her to 'shut the 'f' up bitch'.
I guess I only get involved if it's going to end up like a train wreck. It's like virtual rubbernecking.
