The cash bar thing has most of this handled, but this is slightly different. We were going to have one of the young men from the church youth who is saving for a mission trip work as a coat attendant for our winter wedding. My idea was we would pay him very well, but also put out a tip jar with a sign that says something to the effects of all proceeds go to fund his mission trip after graduation. My mom is butting heads with me on this says its tacky. And I guess I can see her point, but really is it so bad? It's going to a good cause after all.
