Heh...all my co workers and myself were swamped with "guests" almost all the time. If you stayed in the "boat" you'd get asked questions about the non-contract mobile phones, videogames, ipods, cameras, televisions, stereo systems etc. And since I was seasonal, I was given almost NO training in any of these products. I learned by asking my co workers.
Worst part of it all was whenever you'd go and get something for one "guest" and a dozen more swarm around you for their attention.
For me, the best place to be was the "MMB" area doing "reshop". It was much more quieter, and much less stressful...although I soon began to detest the fact that so much "reshop" began to pile up due to "guests" always changing their minds at the front counter or could never be satisfied with what they bought or were given.
