Professional movers often have packed schedules. This is especially true during the summer months, when more people tend to switch residences. Movers often don't have much time to take a lunch break or make a quick trip to a convenience store to grab a drink, so be sure to have refreshments on hand. Go with portable food options like energy bars, and have a variety of beverages to offer thirsty workers. If the weather's hot, make sure you give a few bottles of water or sports drinks to each worker because they'll definitely need the extra hydration.
