I recall one restaurant, completely empty one night, with the front guy sitting resigned wth his feet up. A couple walked past, had a quick glance and carried on. What can you do to get them in? Not much perhaps.
The guy looked up at them, and said "You think my restaurant is rubbish, because there are no customers here". The couple immediately showed their British courtesy and assured him that they didn't think anything of the sort, and that they were further sure that is was a wonderful restaurant, just having an unlucky night. Within a minute he had called their bluff and they talked themselves into eating there without really knowing it.
When they sat down another couple decided to come in and soon it was quite busy.
That isn't hassle, that is class
