I would, but it would depend on the circumstances. I have certainly had the gift of time from friends - helping me move to a new town 100+ miles away - they packed me into my rental van, drove me to my new home, unpacked me, then drove back to their homes. I couldn't afford to pay their gas for the round trip, or buy them lunch, but they did it anyway. And in that same low economic period, when we'd go out to dinner (it was a large group thing), I'd be eating the "soup & salad special" or something equally low priced, because it was all I could afford, a steak dinner would show up for me. No-one would fess up to knowing who paid for the steak, but those were some of the best tasting steaks I've ever eaten.
