How classy was my Wimpy

The thing that always gets me in this film is that although its featuring of a burger bar (at a time when such things were novelty in England) is prophetic, just how "classy" the old Wimpys were compared to the modern burger joints. Alright, it's not the Ritz or Claridges, but you get waitress service, properly cooked burgers etc, and not in cardboard and styrofoam. They probably even gave you a knife and fork too. You even get to order how well done you want your burger to be. (Although the coffee was foul in England until the 90s...)

When the Devil says "I'll cover it in Wimpy Bars" at the end, he was foreseeing an England infested with McDonalds and Burger Kings... but not of the type in the film.
