I guess it seems that a NORMAL person would understand, there are some places where bringing kids along is not only inappropriate, but clearly an excuse for the customer NOT to have someone watch them. Like bringing them to the gym (and I mean, a workout place) or to your workplace (if it's an office) or to your lawyer's office. Stuff like that. If you're a high-end restaurant, with cocktails and pianos playing.
THAT, I completely get. If I went to a place like that, and they allowed kids there, I might not return, and I have kids and have had them all very young at one time. Even though they were very well behaved then - and I am not bragging - I can't imagine frequenting a place that WASN'T a family restaurant with kids screaming, whining, or worse - running around (one of my best friends did that - let his child run around the restaurant when the kid was finished eating).
