Some of the worse is when a shop has several employees working changing one vehicle's tires: one to remove and install the rims, one to mount the tires, and one to balance the wheels. The best way is having one person work the job from removal to install. I know the head of the shop where I go and I always slip him a twenty when I get new tires. He sees the job from beginning to end and that includes a four-wheel alignment.
