My coworkers were very pleasant. A typical day at work consisted of back to back tours. The script allowed for minimal naturally occurring interaction with guests. It gets you used to talking in front of people, but I found it was very mechanical. My boss was professional and understanding, although not especially approachable. But, I have rarely had a boss who is professional, yet approachable.
She placed me working with the same person everyday of the summer because she sensed we were acquaintances. The woman, although kind, was twenty years my senior, and I was rarely placed with coworkers my own age. This added to the lack of variety.
