Is that your experience with it?
When I was in agency it was outcall only. Incalls were concidered sitting ducks to be raided.
But as an outcall provider who sets their time, and cleans myself up to get dressed and ready to head out only after the timers sounded, it has happened many times it takes me about 15 minutes to just clean myself, reapply makeup, get dressed. That's focus on myself alone. I can't imagine cleaning a location, and trying to push a client out who wont leave on top of all that.
The 15 minutes doesn't even offer her a chance to use the toilet between a booking if she wants to stay on time.
I give myself 15-30 minutes just to prepare/clean myself after an appointment, and it isn't even my place to clean, I have just myself to worry about. I hate the idea of rushing while on my own time.
But I do have expierience with corporate time, and it is always not enough because you arent a human to a corporate entity, you are only a means of finances to exploit to them.
