EGKB,
To add to LD1's post, when I was circuit bashing (all lesson in the circuit) I was regularly clocking up 7/8/9 touch and goes. These days I usually do a couple at the end of a lesson. Its all part of training i'm afraid!
To put it in context, I completed 117 T&Gs before going solo...and still do both solo and dual circuits.
As an aside, I do not pay landing fees at my home airfield at all
(Visiting civvy aircraft have to pay around £40 landing fees!)
