That has just made me wish I kept cards..
I save all the numbers in my Blackberry and then notes or code depending on who it is. If someone calls me who has rung before I know before I answer who it is, whether I've met them, whether they book and cancel, if they have terrible english, are obviously having a wank etc. If I've seen them then I put the date of their last booking and how long they stayed for too. Its amazing what you can fit into just a few characters and its enough to give me a heads up on whether I want to answer and how to handle them. It also lets me filter out anyone I save as a TW and also to tie up phone numbers and emails which is handy when people swap about how they choose to contact me.
The codes kind of look like this:
Andy nice, oldr, hj no f. 07/11 1 - Nice older chap who likes a hand job only and I last saw in November for 1 hour
Tom, tll, asi, frantic kiss 16/12 2 - Tom who is tall and Asian and kisses like a suction pump on double speed. Saw in Dec for 2 hrs
John flake tk dep 26/11 1 - Bloke who books and cancels a lot but is fine when he actually shows so if he calls, take a deposit
Tony sub fs 03/12 1 - A sub who likes face sitting
Anyone I've seen and liked gets a * and there's even a few who get ** - but if my OH ever asks why I'm going to have to make up something because they're the ones who are REALLY good. Sssssh though, thats secret!
