More like you went to your favorite restaurant and wanted the fish but there was no price on it, and when you asked how much it would cost they would ask if you had insurance or not because that would determine your price, so you say no insurance and they say okay well it could cost anywhere between $10 and $1500 and then you get the fish and enjoy it and they give you the bill after and it's actually $10,500.
Don't forget the social shaming where the waiters act like you're ridiculous for possibly caring about how much the fish might cost. No well defined consideration means there is no contract. No contract means there is no legitimate basis to bill for anything more than reimbursement of costs that have been actually incurred.
