Although it is not technically necessary to tilt the tilting motors, it is common, so we do recommend it. Crew members are generally tipped at the end of the move, once they have performed their final service. Trainor recommends tipping each moving company individually at the end of each day to avoid the possibility of a leading moving company being dishonest. Consider the difficulty of moving, the level of care that carriers take when transporting your belongings, and the overall performance of the moving company.
But what about your carriers? When thinking about how much to tip people who move to show their appreciation, another way to make them very happy is to feed them. If moving companies don't seem to be working hard to find a solution, this is what you should use to decide whether to tip them or not. Nobody wants to go broke by tipping moving companies (moving is already quite expensive), especially when they consider that a good job hasn't been done or that moving companies don't agree too much.
