I put my keys and wallet on top of the fridge when I used to have to go to the office. When I first started living with my wife she move them for a week to where they were “supposed to go”. I forgot my lunch most of that week. I quickly established that the fridge was the “correct” location and generally never forgot a lunch after that.

If I’m entering a place that has food of any kind I’ll just ask what they want, I’ve rarely been asked for something that exceeds $5-10. More often than not they eat, pack up their stuff and leave after that. They feel acknowledged, I feel good for helping and I also hopefully didn’t contribute to the drug issue.
