Tried booking her a couple of weeks back when she was last in Cambridge.
Emailed the day before, usual brief stuff including 'what is the best way to book' (I'm sick to fucking death of second guessing this). She replies with please submit a booking request which I duly did for 2pm.
Next day it was read about 10am but not confirmed. As it happens I was going off the boil and thinking if you can't deal with your bookings I'm not chasing you and a shit punt probably awaits. About 12:30 I get a text stating that she'd only just seen the br (bollocks) and I should have sent a text to make the booking

Text tennis followed along the lines of
'you told me to submit a booking request which I did'
'only just seen it, can't be on the computer all the time, do you still want a booking'
'no, too late to think about traversing Cambridge on a Friday afternoon'
Quite pleased I kept the punting stash in my pocket.
If you want to book her my advice is to send her a text, email, booking request, fax, registered delivery by royal mail, telegram and carrier pigeon just to make sure.
