Or precious Liam tripped the waiter because you all had him running around in the restaurant and refused to get him to sit down, but hey, its the waiters fault somehow

I've been the waitress in this type of situation. Back in late 2007/2008 I was working a few shifts a week at a pizza place - parents and two kids came in on a busy night, their son was wearing Heelys and kept skating around the dining room. I asked him a couple times to please be careful, within earshot of the parents, because their table was right next to the area where I had to pick up pizzas to deliver them to tables - kid skated right into me and a hot pizza fell on him, the parents threw a fit, and the family had their entire bill comped. I'm pretty sure that the only reason I didn't get fired was because the table next to them told the manager they'd heard me tell the kid to be careful and saw him slam right into me as I turned around from the pizza window
