The £2/£4 barcrests like Top Tenner were surely some of the worst, yet they took far too much off me as a student in 1989.
Playing them again now I struggle to see why I persevered - basically it's a slow death hoping for the once in a blue moon £2 repeat to go four or five times. I could easily lose a tenner in one, and given that beer was at most £1 that's a heavy loss!
