Come to my soi in Ekamai, Bangkok. Every morning 2 guys walk out of their house, jump on a motorcycle, drive 30 metres, pee on the wall and drive home again.
# men walk out of their house and pee on the wall.
All day long people stop and pee on the wall (and I have seen defaction once).
Taxi drivers throw their bottles of urine in the bushes. The whole area is rotten with stale pee.
It's easy to pick on the foreigners, but many Thais are much worse.
