I'm a firm believer in casino credit (markers). I don't like to carry cash and have had two life or death battles---1 in Vegas and one here in Chicago. I also used to maintain a bank account in Vegas so that I wouldn't have to transport cash to or from Vegas.

I suppose that if one is weak and goes deeper into their credit line than they should it can be troublesome. But if someone is that weak, they will find other ways to go too deep, whether it is credit cards, ATMs or whatever.

It is 30 days free interest, and it did, in the old days, result in much better comps.
