I'm pretty well set on the rules I should be following in regards to tipping most of my vendors, like the caterers. My question is, should I be tipping the crew that delivers and sets up our tent? We're renting a large tent, tables, chairs, etc. The crew will set up the tent but we are responsible for dealing with the tables and chairs ourselves. The price we're paying supposedly includes the delivery and setup of the tent, but I think back to when we moved to our new house and we tipped our movers even though we were paying them specifically to move our stuff and it seems like a similar situation.
