You should cancel your credit card immediately and report the loss to the card issuer: if you don't, you could potentially be held liable for changes someone else makes on your card. You should also begin the process of replacing your ID. The bar is NOT liable for your loss of your card and ID--it is not their fault you left them there. They are not required to help you look for them (and even if they do, that won't help if they were accidently thrown out or someone, like another patron, stole them) and will not be liable or responsible for any loss you suffer: the bar is not obligated to watch out for its patrons and prevent them from losing their ID or credit cards. This is your problem to fix, not their problem.
