I did a hotel incall Friday night, got to the room and the door was half open. Took a few steps in and said ' hello' but no answer,
Most wg's will have the door a jar so you don't have to knock. I then thought must be a bogus wg, but had a nagging doubt that something was not right, We had great comms all week and on the day of the meet, Wen tback to my car and waited over an hour, Called her phone, no answer, texted her, no answer, She got back to me today saying her last client had attacked her and she just ran for it.
So 99% of hotel incalls work there will be the 1% you won't have planned on. So always be prepared for a surprise now and again.
