I once had service so bad that as I left I realised I could have got just as much satisfaction (and a lot less hassle) by tossing the money down the grating in the gutter outside.
But it wasn't a "comical " experience. It wasn't funny at all. It was galling. In fact I find it hard to believe how any atrocious sexual service could ever be amusing.
Completely incompetent or bizarre service in restaurants can be. Like the (busy) place in Copenhagen, where the service was glacially slow, and the food was poor. Could I get a bill at the end? I'm still waiting for it after twenty years. I wonder if they've noticed yet?
