The Demon Drink Social life in the West is different from social life in Bangkok. Westerners are more friendly and casual with one another as expatriates. This fact is often celebrated in drinking establishments.
Expatriates are often interesting people who have lived colourful and adventurous lives.
It's fascinating to talk to them. But in bars, not at your dinner-table, is where you'll hear the best stories. There's therefore always a good reason to call in for 'just the one'. There's nothing wrong with the points above. Good fellowship and sociability helps you build friendships and keeps you relaxed in a new and sometimes a strange environment.
