I'm not into booking things in advance as I'm a terrible planner. However I usually get away without any problems. I was around in central London today (Friday) from early morning with a big urge and for the first time not a single one of my hot listed girls had a free slot at a convenient time (not even 'off peak' times) despite being 'available'. This has never happened to me before. Now I've ended up with blue balls on Friday evening and a very hectic weekend to look forward to...
I've done Fridays before without any problems but seems today was just not meant to be...Have you had similar experiences?
