Best "excuse" I ever hear was when I made the "10 min I'm almost here call". I had phoned the escort the day before knowing she was coming to my area the following day.
When I made the call the escort was screaming at the phone (half in Hungarian half in English!) telling me the apartment was dirty when she arrived and that the previous occupants had left it in a terrible state. Condoms under the bed etc etc.
She has spend the morning cleaning the apartment and hadn't been able to take any bookings. She was furious and said she was too angry to work.
I suggested I bring her for a coffee to relax and she agreed. We went for a coffee and a chat. After a while she said she was feeling a lot better and "wanted to show her appreciation".
So she bought me a coffee.... lol
It wasn't really an excuse but it was the truth.............. and she didn't really buy me a coffee...... I made that bit up.
She did something else instead....
