It depends on your definition of "Waste".
On one level, all cash spent on a punt is a waste because nothing objectively is gained and all you are left with is a brief sense of satisfaction which is never quenched for long and a memory which you live with until you grow old and start to forget things.
I remember spending £350 on a threesome which was pointless as both of the girls were not bisexual and it showed during the session. That was a complete waste and I have never had a threesome ever since.
I also spent £1000 on a daytime 12-hour punt which was terrific but that was over 5 years ago and I am now starting to forget as the memory of it is fading.
The most I ever spent was £1350 on an overnighter which was a complete waste because the girl slept for 9 and a half hours of it.
Hadn't you negotiated the t's & c's for that Overnighter, Hobbit?
I used to enjoy Overnighters where the sex continued to the early hours and resumed before cock crow. [Sorry; couldn't resist that!
] However, my last Regular didn't offer them because she didn't want to take my money for the doubtful pleasure of me lying awake next to her as she gently slept!
Other example of waste can include:
money given - when suffering from the delusion of E.A.S. - to a SP who saw me coming - not in the sense I paid her for, of course!; and
not being able to afford to change my car as offer as my neighbours because of all the mediocre punts where I've thrown away £100 - or as we say nowadays, £120
If, as you say, Hobbit, the memory of the outstanding punts fades - and it does - what chance for the memory of the more routine meetings? Before starting this reply, I had a look at my Reviews on here. There were a few of even the
Positives from 2 or 3 years ago where I couldn't put a face - or body! - to the name.
