Be kind to your movers for their sake and yours.

Providing lunch is not just a nice thing to do for your moving crew, it also saves you time and money. A few pizzas and some cold drinks can mean the difference between a 15- minute chow break and an hour-long disappearance for fast-food.

A pot of coffee does the same trick—keeping everybody happy and on site.

Tipping is customary, with $20 per mover a good starting point. Give the full amount to whoever is in charge and ask that person to divide the tips evenly among the crew.

Fantastic service under difficult conditions—lots of heavy stuff, winding stairs, bad weather— may justify a higher tip.
