This has long been the case in Thailand. 25 years ago I went to a BJ bar in BK and was given an excellent CIM/face BJ. Later at bar with my friends said lady arrived and showed everyone her cock. Generally if I'm not sure I apply the "Crocodile Dundee" test. I have had a few BJs from TS having known in advance and really enjoyed them but it's not something I currently look for as RO is important to me at present.
