I mean during COVID as a nurse I paid for my neighbor's groceries in exchange for meal prep (they were single with no kids so it was still cheaper than getting takeout all the time) but that's a highly personal deal to cut. Incidentally though I told one of my coworkers about the deal and they were like "wait my neighbor has kids but I could probably still net positive on like half their groceries..." There were some good human moments during that time. I also promoted that neighbor who cooked for me to husband but that's a different story.
