Do I Look Homeless?

I know I look a little worse for wear after suffering from insomnia most of the week, but this is ridiculous. Ran downstairs and to a Duane Reade in Penn Station to grab a soda for my mid-afternoon caffeine kick. I'm coming back up the escalator outside the building when this guy asks me for directions to Park Avenue. (Luckily he asked because he was ready to walk West and farther away -- it's already enough of a hike on such a steamy, icky day). Anyway, I give him directions, tell him the cross streets along the way, how far it is, how to get out of the maze of corridors to the street, what cross-street we're at, etc. And then he all of a sudden whips out his wallet and tries to hand a dollar to me! He was trying to tip me! I refused the dollar and he kept insisting and I kept refusing... it was so bizarre. I finally said emphatically, "no, it's really okay" and I guess he finally got the hint and stopped trying and just thanked me again, while I escaped to the revolving door of my building. I mean, it was a nice gesture but, sheesh! Do I look homeless or something? Now, if he had been offering me a beer, it might have been a different story.
