I guess it just depends on the location. When I was going through school I worked at another store of the same chain that was attached to a truckstop/convenience store right at the exit of a freeway. We got insanely busy all the time, but a lot of the people were a lot of fun to work with and we had some good times. (despite a manager from hell)
At my store it is easier in some ways because we have a much nicer manager, but most of the people are very boring and don't talk a lot. The one I work at now is also absurdly slow (though many of the employees consider it fast paced) and much larger than the one I used to work at, so it is pretty boring. Most nights we have three consecutive 0 sale hours. That said though, I am a considerably faster and more accurate worker than most here (mostly due to my experience at the other place), so I may soon be a shift manager.

I am not going to be doing this for the rest of my life (hopefully not much longer), but I am at least grateful I got it. I know too many people who cannot find any employment at all.
