The Thai baht is used in Bangkok. Major credit cards are accepted across Thailand in most major hotels and large restaurants but smaller businesses will expect to be paid in cash, as will taxi drivers. Tipping in hotels is not expected, but again is always appreciated, for instance 20 – 50 baht for the porter that carried your bags up to your room, or 20 baht left under your pillow for the cleaner. In all restaurants it is customary to leave behind any loose change in coins as a tip.
