My God, people, isn't it hard for you not to put trays at clean tables?! Why are you removing them from your desk? You eat crumbs under the tables like pigs. There are crumbs on the chairs after you. Don't you eat at home the same way? A constant stream of people at whatever time you come. I feel sorry for the staff for such a very laborious work of 15 hours, as far as I know. People respect the work of others!!
