She makes a fair point there, but those market forces will send punters back to Jasmine if she doesn't make some allowance.
Sonia, would you rather earn £80ph straight in your pocket for once with a punter or, say, £50ph x multiple times with that punter?
I think my second visit to Sonia (when lockdown eases) will be along the lines of "I'll pay you the max you want to charge, but the service will need to be tip-top with some USPs that Jasmine doesn't offer"
