I met this type of guy bashing to nice girl about some mistakes in his apartment bill using very (I mean very) foul language. Seriously he looked pathetic and my first thought was to kick him - he was so rude! Like a rabid mongrel over a kitten. (nice, ha?)
Some compassion and understanding works miracles. Always.
Yes, boarding the train, bus, boat, flying saucer might be a headache in LOS, but they don't mean harm, they are just like that. Accept it, be above it, it does not worth to show your supremacy with swearing and names calling.
I despise those uber-mensch "white world" farangs.
