Beware of a con that is being played in major shopping centers in Bangkok, this lady starts talking very friendly and tries to get some background and recommended to visit a store that is holding a "special" sale jewelry especially , after parting after the conversation and about 2 minutes later another lady comes along and will say she saw you in your hotel where she worked that morning and she also recommends going to this same  store and offers to get  a tut tut. It is obvious Lady 1 contacted Lady 2 with hotel details so if you think you may be being set up just give a false hotel name to lady 1 not the one you are at and you will know when lady 2 tells you she has seen you there.
