Smokes

One thing that is more common here than anywhere is smoking! Have a smoke after dinner, in the restaurant, in everyone's face. Suck one down on the train, in the non-smoking section, blowing it into the sleeping compartments. Crackle one up in the taxi, guesthouse common room, bus, plane (well maybe not plane), or anywhere. As if the pollution wasn't bad enough.
And when you're done, heck a huge gob of phlegm on the carpet.
