I spent many years in customer service, too. I think this gives me a higher tolerance level for the repetitive questions. I am also a very quick typist so it doesn't take me long to respond anyway!
I keep my answers short and sweet and end most mails with "Please call me on xxxx or use the AW booking system to arrange an appointment." 80% of them will never call, because they don't want to book, they're just looking for a cheap wank.
I reply to most sensible mails. Last 10 received:
1. "Are you available at [x time] in [correct location] on Friday?"
I replied no, sorry I am already booked at that time.
2. "I just wanted to confirm the next time you are available for incalls in X is the first week of February? As I see you are touring around the UK a lot in January"
I replied and said yes, but please keep an eye on profile as my plans do change.
3. "are you available for outcall to X"
Replied and said no as I have left that location.
4. Confirming details of a booking.
I replied to confirm. He ended up cancelling at short notice
5. Confirming details of a booking.
I replied to confirm. We went ahead.
6. "You are Devine! May I please see you tomorrow morning? I'd luv an hour with you with lots and lots of two way oral! Your time would be greatly appreciated. Yours hopefully"
I replied to say call me to arrange a booking, knowing he wouldn't. He didn't.
7. "Hey are you free next week for half hour with a 24 year old cock to suck on and fuck you hard ? How do I book a early morning session before work x"
I replied to say call me to arrange a booking, knowing he wouldn't. He didn't.
8. "As you'll see from my profile, I offer services too and have good feedback and pics for you to see. I am offering fellow escorts a free therapeutic, Swedish style massage. It can be just your back or full body. It can be totally innocent or a bit sensual. It's all up to you."
I
ignored this freebie hunter and his copy paste message.
9. "Hi, I know it's late notice but are you available for a booking tonight at 12.30? xx" (sent at 11.30pm)
I
ignored this as I do all other late night mails and texts. Also had been asleep by then for at least an hour!
10. "Are you free tomorrow for a meet?"
I replied to say no and gave him my future availability.
So out of 10 emails, one booking. LOL.
I don't mind so much if they check on prices or services. If I'm buying something expensive then I'm probably going to double check stuff too. Like I can see on my hairdresser's website that it says a restyle and half head of highlights is ?75, but I'll still check the price when I book.
