i have not read all the replies, but as a waitress of 27 years.......
Leave them at home if they cannot sit still, use manners, and used inside voices.
People who secured child care for the evening, who are spending their hard earned money in my restaurant to enjoy a kid free evening do not want to sit next too, or in a room with a child or children who are running wild, banging silverware, using their outside voices or listen to their moms whine "siiiiiiiitttttt doooooowwwnnnnn" at the top of her lungs.
Too many come in, trash the table, let their kids throw their food on the floor, leave a poor tip, and act like it's the servers JOB TO CLEAN UP AFTER HER SLOPPY KIDS.
That fractures me every time.
Or the moms that come in (usually in 3's or 4's) with 5-7 kids that just run WILD while they sip on their wine and talk about how "cute" their kids are.
Had one family, that opened presents at the table. Dad got cologne. One of the wild animals sprayed about 10 pumps of this cologne in the dining room. Imagine the gagging smell of 10 pumps of men's cologne in a very small dining room. Yeah, mom was wasted and dad thought he was cute. Had two tables ask for their checks, and both told the man his kid was bad on their way out. The dad wanted to get snarky with me for what the other guests said.......really.
Unless you are going to a kids place, or they are SO well behaved people make it a point to stop by your table and tell you how well behaved they are......
Leave them at home.
