I certainly wouldn't pay for webcam. If no one did they would either have to escort or get a proper job.
I have in the past, but only with girls I want to see as an Escort, So if she doesn't Escort I wouldn't consider it
Reason been I would rather waste £5 on a cam booking than £100 on an escort booking
thinking her personallity will come out on Cam ie if she can't be arsed or not intrested in what you want with instructions
trying to waste time getting her knickers of etc or trying to bake you for more money by extending
