Extortion lite ? Just a tiny, little, teency weency bit dramatic, don’t you think ? It’s called overcharging and you refuse the service and go about your way. If you don’t refuse then you are agreeing to pay their price. I choose to not receive the service in that situation.
When you drive up to a gas station and note the price of gas you can’t pump your gas then refuse to pay that price. You accept the price or you get a bus pass.
If you started screaming and yelling and interrupted my massage I wouldn’t be sympathetic at all, I would be pissed. I would want the parlour to forcibly remove you. If you wanted you could even call the police, which would be rather amusing.
“Excuse me officer, they are overcharging for extras” !
The funny thing is, this is all hypothetical. You haven’t done this and apparently haven’t had to. All of us plan on being heroes if the situation arises. But most of us put our tail between our legs and run away.
