I've worked in a great many places with the big perforated ones all over the place. I hate cleaning them every night. It's such a time waster and I feel that putting them in the dish station is just a contamination issue waiting to happen. All the nasty stuff that gets clogged in the holes is going into your dishwashing station at end of night. I find it disgusting. As others stated, it becomes an excuse for cooks to wipe stuff onto the floor and ignore it without sweeping.
