YMMV is not acceptable if they take your money. You've completed a business transaction and should expect great service for the money you've forked over. It's not like you are paying them to love you, you are paying them for a good time. And if they don't "Feel it" with the customer too bad. They should act like they do. They have the right to decline your money, if they take it they need to poney up and provide great service. Otherwise they are substandard and should find another line of work.
