The famous night-market of Luang Prabang, Laos. There are many beautiful handicrafts for sale here, but bargaining is a must to get a fair price.
In Southeast Asia, it is common for the salesperson (especially saleswomen) to flatter a foreigner by complimenting him. I think this is an excellent strategy as it makes the foreigner happen and usually results in a good sale. Bottom-line: everyone is happy!
