If you are a business generating rubbish, it is your moral responsibility to account for that rubbish. The business selling stuff doesn’t have their employees filling their pockets with the bulk food packaging rubbish at the end of the day to dispose of at home; they have their own bins. They just don’t want to be responsible for all the rubbish they generate cause it costs them more money than trying to put that responsibility on someone else.
Putting up shelves, you have to decide if you want them to be level, parallel to the floor, or parallel to the ceiling, and those are all different.
