A Self Cleaning University...with Timer

Self cleaning...with timer

A branch of Currys-PCWorld. A couple wearing matching cagoules wander in clutching a copy of Which? They're immediately accosted by a man in a tight fitting suit and lanyard. 

Lanyard Man: Good morning! Is there anything I can help you with today?
Cagoule Man: Ah...yes. Yes, actually. We've come for a university course.
Lanyard Man: A university course? I think you've come to the wrong place...
Cagoule Man: I don't think so. See, we subscribe to Which? We have done since 1947 when we weren't sure which coal scuttle to invest in. Anyway, we saw that as well as dishwashers and vacuum cleaners they are also reviewing university courses. And we'd like to buy one.
