There is nothing more disgusting than standing in the shower next to some other guy who is blowing his nose against the tiles, clearing his throat loudly, coughing up even more mucous and spitting out one wad of spit followed by another onto the floor, not even making a minimal effort at aiming at the drain. There she flies.
Perhaps those kind folks coming from those other southern lands tend to think that this makes them more manly, athletic and maybe even more attractive to the opposite sex.
I despise the idea that my bare feet are sloshing around this odd mixture of unwanted fluids when all I wanted to do after a good workout is clean up and freshen my sweaty body.
