Give away a doggie bag

I've started doing something in the last two years and it occurs to me that it could be a neat thing to spread, especially among liberals.
I travel my fair share on business and often to dense urban areas. I'll often have to go to dinner at specific places. And far too often I end up with extra food. It'll normally get thrown out. I'm staying in a hotel and probably traveling in the morning so there's not much reason to take it with me. Goodness knows I don't need to be eating too much. But lately, I've been having it boxed up and I take it, and as a leave the restaurant, or as I get back to the car or hotel, I'll look for that homeless person and offer it to them. Many times I often have gotten in the habit of scoping out where they are before I ever get to dinner. That guy in a shop entry way, the fellow on the corner begging for change, or the bag lady with the shopping cart full of stuff.

It goes down pretty easy. I usually walk up and just say "you hungry?". They always look a tad surprised but are quick to respond and I just hand them the box/bag and walk away. Some coworkers who are a bit of a right wing type gave me some grief once, but I just said, "What's it to me? The company is paying for my meals. The food was going in the trash. I just figure it's my "loaves and fishes"." Kinda tends to shut 'em up pretty quickly.

I'm tempted on occasion to say something like "It's a liberal stimulus program". But I mostly don't wanna make any deal at all. I make as much a fuss as if I was throwing loose change in a busker's guitar case.
