I found that example odd, as in my experience the amount of bars that don't hold your card while a tab is open is in the minority (I don't go to that many, but I actually can't think of any nearby that DON'T take your card). Sometimes I'll just order and close out as soon as I walk in, sometimes I'll hand them my card and close out at the end, but I've never felt that I was being treated like a criminal

I think they mean specifically if the bartender asks you to open your tab before taking your order and/or pouring your drink. For what it's worth I don't think I've ever experienced this, but I could see it being somewhat off-putting.

I usually hand them my card and ID right when they walk up, so I guess I've never experienced this
