Am I going to jail tonight?

I'm in Vegas for a few days. I'm 20. The date on my ID is messed up. You can't see it. So I was telling people I'm 24, and getting drinks until my drunken *** decided to gamble. I went to the counter to see if the lady can read my date of birth and she couldn't, but she was telling me how young I look and she was wondering how I got the alcohol and when she said that the security can probably read it, I took my I'd and left. What if she remembered my name? can they track my credit card purchases? Am I getting arrested tonight?
