Well I hear what you are saying but for me personally I don't need a sign or a guard to advise me of a dress code in a public supermarket/department store. I must be far more astute then some of the animals I have witnessed. Last month at Tesco Lotus in Lamai Samui I saw a foreign woman walk into the store with a very visible yet tiny thong bikini with the sheerest beach wear coverup. For all intents and purposes she was nude. We were miles from the nearest beach. Signs are clearly posted all over Samui Immigration requiring appropriate dress and I have seen more under boob, moose knuckles and balloon knots in there than I have seen in a proper go go bar. They actually keep a sarang behind the counter so the whores can cover up for their photos. Try that in Phuket and you will be on your way back to the villa for change of clothes.
