Absolutely NO.
There is nothing worse than waiting at a table for 20-30 minutes, for a waiter to take your order on a slow afternoon.
Take a look around the F**king dining room; Does it look like there are tables where people have no service, no drinks, no food. Seems to be a recurring thème with a restaurants hère in Pittsburgh, médiocre wait staff. Work as a team, communicate with your wait staff.
