My phone DID start to ring just as soon as I started to put food in my mouth. I ended up with one hour and then fielded several calls all wanting to come at the same time. I had one guy call for 5pm for an hour and I'd booked him in. Then turned away a handful of others. Just got a cancellation off Mr. 5pm and saw that he'd texted in a timewastey way last time I was here (I hadn't saved his number as he hadn't been severely timewastey and this time he'd called so I didn't see the text thread.)
Have tried to get back to the guys I turned down but I don't think any of them are still interested.
Then some guy called asking for 5pm for a half hour but he sounds a bit... unsure. I've accepted the booking and written down his number and I will bump him if anything better comes along. When I'm working in the City I get a little more ruthless with my bookings - not quite double booking, but definitely staggering arrival/confirmation times and cancelling if necessary. Well, I'm going to do that for the rest of this week.
