Flip-flops

I don't think there's any need for flip-flops. I hate that stupid 'schlop-schlop-schlooop' sound they make when people walk in them.

At the beach, its annoying but you think 'okay, fair enough they are beach shoes', but people wear them in cities etc. Why? They're not really appropriate footwear, are they? How many peoples toes have been trodden on because they've worn beach shoes anywhere other than the beach?

A little (read- fairly big) part of me is tempted to stand of the back of them if I'm going up the stairs behind someone who's got them on. Mean I know, but then they might start to wear appropriate footwear. So in a way it'd be the right thing to do, it might save them getting their toes stamped on at a later date.
