I lived in Leicester for a number of years. This UK city is host to a huge percentage of different races and some of the habits are a bit off-putting to us.

Blocking one nostril and blowing a torrent of snot out of the other one in the public toilet sinks. We find this disgusting but they're adamant that blowing snot into a handkerchief is abhorrent...

Crapping from a great height by standing crouched on the toilet seats rather than sitting on them...

Funnily enough spitting is a habit here in Spain as well, although confined to the older generations.
