I have seen TS pull off (or rather tuck in) a full naked private and the customer left seemingly totally unaware (he asked if she had children) that he had just been entertained by a man.
I have also refunded many shows to customers "scarred for life" by the experience.
At the end of the day, refusing TS could be considered discrimination, but letting them in, in a clearly marked section, may end up paying dividends.
You may be surprised at how many otherwise "female prefering" customers can't resist the odd look at a cock.
