Ugh, my stomach turned when I saw that picture, but not for that reason. This would be hell to deal with as a concessionaire. You wouldn't sell a whole lot of them to get proper stock rotation unless you only sold them at a few concessions stands in the park, which means you get less publicity/availability, which results in lower sales.
Question for you guys. Do you think items like this actually draw sales? Would you not otherwise purchase concessions if this item were not available? My thought has always been to offer as little variety as possible (within reason) to save on overhead, because people who buy snacks are going to buy them regardless.
