Greetings in the Apple Store

Sitting in the Apple Store for hours yesterday it did not take long to realize the ones in the red shirts that had the Apple logo on them are the help, or they probably prefer to be called "Part of the Team". Watching them talk positive and interact I think they get positive group pep talks. From time to time I noticed as some passed each other they would give each other a High Five. It was almost like a salute. I always thought "High Fives" are pretentious or superficial. I wondered if instead they gave each other a whack on the ass it would be just as effective?
