Used amongst
employees of the service (bartender, waiter, busser, etc) field. Meant to bring
attention to a certain customer present at a table, booth, counter, or elsewhere within the property for a visually obvious reason without arising
suspicion amongst the patrons.
Busser:
Silverware check table 85.
Waiter:
Holy shit, you can see her tits from here!
Busser: Silverware check the bar top,
pretty sure the female at the end isn't old enough to order juice, let alone a drink.
