This usually lands me in all sort of drama. Had to cut off 2 of my regulars. Arranged a 3s with them (say A and B - both advertised as a T only), notice heavy chemistry between them that evening. Fast forward couple weeks, met with A who told me that he had actually went back to B's place after the 3s and B had bottom for him. A went on to spill tea on B. Being curious myself, I book B for the week after, surely right on cue B start babbling about A (including that A had bottom for him). All fun drama until B snitch on A for whatever he told B about my personal life (go as far as showing me A's texts).
One other instances, arranged a 3s with my new regular (C) and this one other provider (whom I have never met (D), recommended by C). Again, heavy chemistry between C and D, though expected as D was recommended by C. C was booked for 3hrs and D only for 1hr (his booking ends on the 2nd hr of C). C ended the evening early (at the same time as D) saying he is double booked with other client and C promised to replace that 1hr for the next day. Annoying but since I was spent and tired that evening, fine with me. Fast forward weeks, I booked D and to my surprise D let it slip that he had actually went home with C that evening (hence C ended his booking with me early). Had to cut off both of them.
