Of the food items we sell, it goes Nachos, Soft Pretzels and Hot Dogs in that order.
Of course, we have sold Nachos for a lot longer than the Pretzels or hot dogs. On busy weeks we sell 100 + pretzels a week and about twice as many nachos, maybe 50-60 hotdogs. Of Course that is really busy weeks, which we haven't seen in quite a while. But I can't say that I regret adding any of it. And the mess really is no worse than popcorn or soda spills.
I was also wondering what kind of cheese you have that has a shelf life of 2 weeks. The cheese we sell has an opened shelf life of 4 days. Normally, we have no problems selling a bag in that amount of time.
