When everyone is sitting down and an instruction is given to do something which involves standing up then everyone waits
around for the first person to do it.
The boss tells everyone to get up and go to the front of a room. No-one moves. One guy says to the next “This is a total waiter”
Waiter: define #2
Someone who unobtrusively hangs around a place of business that often has a large volume of customers (supermarket, department store, hotel, etc.), and watches for opportunities to “scavenge for leftovers” and otherwise save money on stuff that he can utilize in his own life. Examples of these opportunities could include finishing/gathering uneaten remains of a family’s meal after the group leaves the table, catching an opening/closing door of a coin-operated restroom to keep it from latching when a paying restroom-user is exiting/leaving so that the waiter can slip in and use the facility without having to drop in his own quarter to get the door unlocked again, etc.
If a waiter is part of a sizeable low-income family, several members of his family may be recruited to discretely hang out in various locations around town, so that multiple scrounging/money-saving opportunities can be simultaneously observed on the same day. For example, the husband might sit quietly in a corner of the local service-garage and ask customers for their used motor-oil so that he can take it home and burn it for heat in his specially-designed furnace, while the wife and/or older children spend a few hours at the city park and watch for fellow relaxation-seeking visitors to toss returnable beverage-containers into the area’s trash cans.
