Oh my God! You had every right to send them packing! It doesn't matter who they are, anyone who acts like that deserves to be out on their ear! You were totally justified! Good for you for standing your ground!! It is even worse that they knew in advance how expensive that place is and expected that they could make reservations, show up, and you would be so blessed that they graced you with their pioneer presence that you would foot the bill? Un-freakin- believable.
