My point was that due to the rising cost of living the demand for SPs would be less (in other words, punters would forced be to spend their money on rising energy and food prices leaving no money to spend on ladies). Given this, the demand for SPs would be less forcing SPs to, in turn, lower their prices.
You would hope that would play out. Also possibly the hope of more girls entering the fray if finances are tight and they are looking to supplement their earnings.
But there are probably more forces at play...pre-Brexit there were a lot more cheaper touring EEs soaking up some of the demand. This supply has shrunk with now mostly pricier Brazilian girls touring out East.
Also the online market took off over Covid. Lots of potential new working girls are making money showing their pussy on Onlyfans, etc, leaving less for the in-person meet market.
So although the demand side has undoubtedly shrunk with the cost of living crisis, the supply is probably tighter too. The market will always adjust to the supply/demand balance, so if you're seeing prices go up, it is likely that any reduction in demand is being countered by an even tighter supply.
No idea about Shannon, but well-reported English girls have always attracted a bit of a premium.
I guess the only thing you can do is look for value where you see it and abstain if you don't, you definitely can't wish the prices down, it always finds its own level.
