I remember it well. I think it was made by ATV in Birmingham....but I may be mistaken.
Correct, and starred the omnipresent (as far as AT.V. was concerned) Noele Gordon. There was a satirical series which lampooned it, can't remember the name - it centred around the cleaner and faithfully reproduced the (many) shortcomings of the original.
Crossroads was one of a number of programmes where, after a change of scene, there was often a noticeable lag before the actors started moving - presumably they waited for some command. I would have thought that an actor sweeping the floor, for instance, might have started moving before the scene was being transmitted to avoid this, but...
Bizarrely, there was a real Crossroads Motel in Weedon, Northamptonshire, where the A5 and A45 crossed. I actually had (blagged!) a meal there once, pretty good. Not sure why they didn't change the name to avoid the obvious comparisons.
