Ummmmm 1st date etiquette question...WTF takes their kids with them on a first date??

Had a date with Jill tonight. We had agreed to have some dinner/drinks and watch the game as she is a big sports fan. I had emailed her and said "Hey lets get together at Applebees for dinner and a few drinks and watch the game". She emailed me back and said "Yah, I'm free, that sounds great!" No mention of kids...perhaps I should have clarified

I had a work function nearby so I was there a little early and had a beer at the bar. 7 comes and goes. I get a call from her saying she's running a bit late but would be there shortly. No big deal, I'm chatting it up with 2 girls who were out for happy hour drinks after work themselves. Next thing I know, I get a tap on my shoulder and hear "Matt?"I turn and see Jill and right behind her are her 2 kids

. I honestly didnt know what to say. I said in my most uncomfortable voice "Uh, Jill? Heeeeyy...uh and they are??" She introduces me to "Little Johnny" and "Little Suzy". She then pulls up the chair next to me and the kids are just standing there looking at me like I just killed their dad. I get up and offer my chair to one of the kids and she says "No, they're ok". I hear the 2 other girls sort of giggle and then they got up and left shortly after that.Im completely dumbfounded at this piont. But I honestly couldn't bring myself to just get up and leave. We get a table, order dinner and I'm just squirming with discomfort as she works with the kids to figure out what they're gonna order. Finally once her attention is away from her kids, she begins to talk to me. The conversation was entirely about little Johnny and little Suzys first week at school. I ended up talking to the kids more than I talked to her I think. Not one mention from her of "I'm really sorry, I couldnt get a sitter" or "They had to come at the last minute because of <excuse>"...like this is standard operating procedure for her.

Finally dinner comes, I've been paying most of my attention to the TV as the breaks in conversation were getting farther apart. I'm doing my best to ask her questions but I kept getting interuped by "Johnny stop it" and "Suzy, take 2 more bites". Luckily after dinner, she paid for her and her kids. It was the most awkward date I've ever been on in my life. After the bill was paid, I politely excused myself and said I had to get going. I shook her hand and said it was a pleasure to meet her and booked.Do people seriously do this???? I'm completely shuked.
