As discussed in another thread, opinions seem to vary, so I thought I'd try a poll. Would you like your provider to contact you, perhaps thank you for your meeting?
... then ended they contact me almost every week ... im thinking of one in particular that got too comfortable and service was affected so i had to end it...too bad we had a lot of fun together
Personally if a meeting went particularely well I let the gentleman know to feel free to write me to update me on how he is doing, even if it's not about a booking, just because i'd like to stay in contact.
This opens up the lines of communication, and if the gentleman write to say hello I know that it's ok for me to write him from time to time to do the same
