I'm having the exterior of my house painted. The crew is great - the guys are friendly, industrious and neat. I would like to tip them when the job is finished if that is appropriate. There are five of them, one is the foreman. He does as much work as the others. Would I give him more? I can afford $50/each. If that's not enough I won't tip at all. I know some of them personally and they could use anything extra.
Thoughts or advice?
