Restaurants/bars re-opening will have one of the biggest challenges as the goal for profit maximization is a large robust crowd inside while some are willing to wait 30-45 minutes outside for tables. They too must deal with hand sanitizer, masks, gloves, and extra disinfectant products. However, restaurants also have menu issues as many touch and re-touch the same menus. Some have suggested throw away menus but this too has a cost. The establishment must print hundreds if not thousands of menus weekly.
