In order for an agreement to be legally binding, there must be "consideration". Consideration is not whether or not they were kind to you. It's a legal term that means a good or service was exchanged for a monetary instrument.

You cannot commit to consideration while not being in your right mind (intoxicated) or under duress.

Dispute those charges. The strip club is out maybe $300. You're out $10,000 if you don't.
