The way most new American stadiums are constructed these days, especially baseball. Atmosphere killer though because people are walking around all the time.
What happened to people coming to you in American stadiums in order to sell food?
I know we tried it for a few seasons, was pretty s*** when you had to pass along your money down the row and hope you would get your pie back without anyone taking a bite out of it and a fiver wouldn't go missing out of your change.
Still do this. It's typically for just beer and snacks (pretzels, cracker jacks (at baseball), hot dogs). The other food requires a trip to the concourse, unless you're in the expensive seats. Was lucky to sit in those for a couple Yankees games last year. Raise your menu in the air, waitress comes down to take your order, swipes your credit card, 15 minutes later you have a couple beers and a hamburger without missing a pitch. It's pretty great.
