true enough. i live in an area of bangkok where restaurants don't stoop to such practices, the menu price is the price, want to tip? up to you. a, foreign owned, restaurant opened a couple of years ago, when the bill came they had added the ++ amount, i told them they were being misleading, that i would pay the difference but would never use their restaurant again - i enjoyed giving lots of business to the restaurant opposite. i suspect i wasn't the only one as they went out of business around six months later.
