Love how some folks are "I'm a parent and I'm bum hurt by this. You don't have kids so your point is clearly invalid. Deal with it.".
Fuck off.
I deal with it every single time I go to a decent resto and have the misfortune that a bad parent decided to bring their bratty child out. After the 2nd annoyance coming from their table I usually call the waiter and tell him I will have none of that and ask him politely to do something about it. I always get it my way either in the form of a table change (which I'll perform and have direct eye contact with the parents at the table), get
their table changed, get freebies from the house heck even free meals... or in one case confront them if they weren't willing to do anything about it.
This last case was special. After enduring the first 15 minutes of a child crying and being COMPLETELY IGNORED by their parents more interested in having their romantic conversation. Other tables clearly looking annoyed as well with many of them giving dirty looks. I eventually got up from my table while we were quickly discussing another resto to go to for the evening, walked over, stood over them and called my friend at my table and started talking loudly on the phone while I towered over the parents. They looked at me perplexed while I was there as I was in my conversation. My friend over at our table was in tears over it. They tried to ask what I was doing but I ignored them, pretending to be engrossed in my useless conversation. When I eventually hung up on him after 3-4 minutes, I looked down while the family was staring up at me, transfixed by what they saw. The nearby tables were quiet and even at this point the little infant was perplexed as well and was finally quiet.
I said: "Are you annoyed? Good. Now you know how our table feels over there along with every table around you (everyone was at this point staring at this table) with your child making so much noise and the shitty service in this joint won't budge a finger to do a thing about it." pause for dramatic effect "I figured I needed to find a way for you to realize how much of an inconvenience this situation is for a lot of other people who didn't expect to be your babysitters tonight."
I walked back to my table and sat down.
They left 5 minutes later after their bill was paid and their food stuffed in a box. The woman was shamefully embarrassed and looked the ground and the man gave me a heavy angry look. I shrugged. The wine tasted great and I got several approving nods from people from the other tables.
I don't have much sympathy when you bring kids to a resto beyond the audience for it. I don't usually go to a suit and tie resto nor should I be forced to. I'm sorry you folks are bum hurt about it. However, I don't have to have to endure your poor decisions.
More restos should enforce this policy.
If you don't agree with this, it doesn't fucken matter to me.
