You know what the real difference is?
When I go out to eat I always try to pick up the check. My BIL and I have almost drawn blood fighting for it. I figure if I'm going to eat with you, it's because I want to spend time with you and I don't mind paying, it's not an issue. Sometimes I'll pay, sometimes you'll pay, sometimes we'll split it evenly, sometimes there will be separate checks, because yes, around here you are asked that at every restaurant whether the little breakfast joint or Ruths Chris.
The major thing is, I'm just saying what I do.
I'm not saying this is what I do and me and everyone I know could not imagine the strange, weird, cheap way you do it.
It's not the way everyone on this thread has answered the poll, it's the tone the 16% has used in implying their way is the only "classy" way to do it. If it's done any other way, well, you all are just not as civilized as us. Some folks are implying it's horrifying to do it a way other than theirs.
But a lot of us are just confused. I know you don't see my comments that way, but for me, I have never seen it, don't know how to handle it, and am not insulted by it. I'm just confused. As I explained up thread, I was out in Pittsburgh this past weekend and learned for the first time that an establishment will take multiple credit cards for one tab. My friend literally had to explain it to me. My husband and I discussed how much money to bring prior to dinner because we knew we'd be splitting the tab and we couldn't use a credit card. It never, ever occurred to us that a restaurant would take more than one credit card for one tab. It was an eye opening moment.
But realistically, and I don't mean this in an insulting manner, I am not sure if a waiter would split a tab. It's just not done around here. I've also never seen someone ask for it to be done. It's not a matter of right or wrong or class. It's just not done. Edited to add: Actually, I'm going to ask as I dine out from here on in. Maybe it is done and I"m just not aware of it.
And finally, I like the way we do things. It's not right or wrong. I just like it. And honestly, I've never been caught in a situation where I've felt ripped off. And I've never ripped anyone else off. Others, though, have had that situation and feel that their solution alleviates it. If I had been in their situation, I might feel that same way. I do know that I would NOT be going out with a party who deliberately tries to stiff me. I'm sorry for people who are caught with family members who do this. I would not dine with them because I only dine with people who respect me. But I can see how family can screw you in situations where you have no control.
I'm from South Texas and would like throw in my two cents (separate check 
So, I guess if everyone's cut is $23 they should all just toss in $40 and call it good, right?
