IMO
When girl opens door, usually living room area will be quite bright. Stop and check her face out a little bit. Look at her feet, look at her body. If not up to standard go into room just tell her not ok. Most of the time she will understand and tell you to "tell my boss you not ok".

If I suspect at the start is that the girl is transgender or ladyboy-like, most likely won't have much mood to continue anyway. Might as well just quell whatever urges at that moment and just leave. Text the okt and leave.

Once downstairs, light a cigarette and tell yourself that a not so pretty girl > above average transgender. Then carry on to book another alternative. Trust me, you'll be happier.

Just my 2 cents.
