I’ve worked on both sides of the house for 14 years and I’m in management now. The issue is once you open products, not when they’re sitting there. Sitting there is also an issue, however, as stock that doesn’t move still incurs costs. I work on the institutional side now and we only provide nonalcoholic beverages, but they are either single serve or cheap bulk prep. These are not what people are expecting at a restaurant. Many items in cocktails also have long shelf lives after opening or are cheap/move quickly.
