I used to work full-time retail, and it always seemed that as soon as I started walking to the breakroom, at least 10 people would stop me for help. Apparently I exuded some kind of "on a break" aroma that made people want to interrupt it. The problem was that I was usually on a strict time schedule, whether for lunch or otherwise, and even a few minutes on the floor meant a few minutes less for me to get a break.

However, I do agree that the least the employees could have done was called someone to help. That takes what, 30 seconds? When I was stopped on my way to a break, my usual response was, "I'm sorry; I'm actually on break right now. However, I'd be happy to get someone else to help you."
