George and Lynne arrive at a restaurant. The waiter asks them if they would like their usual table and George is impressed that he remembered. He then offers them two dishes and George is again impressed that the waiter remembered. George and Lynne are then doing the dishes because George did not remember to bring his wallet.
George and Lynne have been to this restaurant before. As they have come back it would be safe to say that they enjoyed their time here. It seems that either the steak and the scampi are specialities of the restaurant or that they were just very good as it seems quite a big deal to get dressed up just for steak and scampi. Perhaps steak and scampi are the height of sophistication for George and Lynne. They just aren't as high-brow as we had them down to me. However this could be one of those restaurants that take a classic dish like steak or scampi and puts their own spin on it.
As George and Lynne cannot afford to pay, in classic cartoon style they are doing the dishes. A dishwasher in 1983 would probably be paid about £3 an hour. If this really is a classy a restaurant as we think it is, then their meal could have cost upwards of £50 between them. In order for George and Lynne to pay off their bill, they will have to wash dishes for the next eight hours. It would have been simpler for George to drive home and get his wallet while Lynne waits at the restaurant as some sort of collateral. If he doesn't return with two hours, they are allowed to shoot her.
