So I took a booking a few weeks ago for today. I don’t mind advanced bookings and he paid the deposit . I tried to confirm last week and it took two days for him to get back to me. I text this morning to check, saying I need to know by x time and still nothing.
He’s a new client. Would you carry or cancel? I have a regular who would take that slot but he needs to know in the next hour. It could be several hours until
I hear from this new client.

I’m having lots of people who seem to have never booked an escort and it’s showing!
What would you do?

I'd definitely go with the regular, you've done your best with the other guy so not your fault if he misses out and you get to keep his deposit too, so win win.

When you accepted the booking what did you say to him regards confirming?

I always tell them how and when I need any confirmation, and put this in writing so I can go back and check.

I do hear that some Escorts do not ask for confirmation, and some punters do not like it. I was quite lax on it at first but I learned I need to know, and some will not ever tell you.
