It sounds like you've never worked in a grocery store. I did for 6 years (all of high school and 2 summers during college.) When we weren't on the register, we were almost constantly mopping from spills and broken jars. In a store with older equipment, even the coolers in the produce and frozen department will cause minor condensation on the floors (most grocery stores have rubber mats in those areas specifically because it would be a full-time job keeping up with it otherwise.) It was certainly a t least a 2-3 times a day occurrence. The reason is pretty clear: grocery stores work on such slim margins that even a minor lawsuit from someone slipping or being cut on broken glass might be the end of the store.
