We used to have this dude that would sell bags of food from a local store named Henry's, which was basically our Trader Joes. His fee was always the same no matter what he gave us:

Twenty dollars, a glass of water, and a cigarette. In return we got all kinds of good shit from steaks, sausages, deli meats and cheeses, cookies, juice, etc.

I always wondered how he did it but never asked. Or cared lol.
