Did they tell you the comp would be $400 prior to closing the door? If so, then I would say you had an oral agreement and it would be pretty unethical for you to claim anything else.

Now if they didn't tell you the comp would be $400 beforehand, you are lucky that you didn't end up with a $10 meal voucher -- and that's it! Yes, reports are that that was the offer once last week from COdbaUA.
