I’ve mentioned before that I sat on top of a scaffold in a bike shop for a week doing a mural.  It was interesting to be the proverbial fly on the wall, and see the different ways that different employees interacted with different customers.  There were variables everywhere- time of day, personal or by phone, male or female, kind of bike rider, general personality of the employee, general personality of the customer… it was a subtle dance, each interaction unique.
