Bob, I literally stopped being friends with a couple because they called me up and wanted to go to dinner, we agreed to meet up at one of the nicest, trendiest places in town, and they showed up with their two children, both under age 4. The oldest proceeded to run around and scream he wanted fucking mac and cheese and a hot dog the entire time (at a James Beard semifinalist's neo-american foodie restaurant). They had absolutely no shame in this. I pretended I had to go to the bathroom right as they left so I could find the waitress after they were out of sight, hand her an extra $60, and say "I am so sorry, I didn't know. I just didn't know." She nodded.
