Do you wanna know what we do with your drivers license number? Nothing. But we are required to put it on there in case you come in and spend more than you should have and then call us saying someone else used your card. Well, if your license number is on there that's our way of proving that someone who looks just like you was in here with your ID and your card that night. Hmmmm..... It is for your protection too. No customer is allowed to use a card that does not match the first and last name on their ID. If you drop your card in another bar or on the street and someone picks it up and tries to use it at Logan's they won't be able to. Lastly, it is a second line of defense against minors. If for some reason a minor made it past the door with someone else's ID and then try to use their own credit card they're busted!! Really, bartenders there put up with enough, and we love our jobs, but don't give us a hard time about the ID thing. If it bothers you that much bring cash. We have an ATM machine too. Cheers!!
