Definitely less tolerance to disability and general out of control childish behaviour and so parents who can't control their kids for whatever reason are far less likely to take them to places where that would be noticed.
I was raised much the same way I think many French kids are raised (and we did spend a lot of time in France...)..
We were expected to sit down and be quiet, our presence at the meal was tolerated and only on the proviso we did this - we knew if we were noisy/couldn't sit still/interrupted adult conversation, we would be swiftly removed from the venue and put in the car and generally, left there or if not suitable, parents would then tag team the meal/minding the kid.
That did not happen very often, I think because we knew the consequences would be carried out without any messing about and because we knew we were not the centre of attention, we were there out of necessity, not out of desire to spend time with us, talk to us etc.
We did not interrupt, because we knew we did not have anything valid to add to the conversation (and if we tried and said something stupid we knew about it PDQ) which put us off and taught us to shuttup and listen!
I don't know that harsh threats and humiliation is the ideal way to educate children, and it wasn't always that harsh, in that we were also taken to eat out at more relaxed venues, on occasions when our presence was actually wanted rather than merely tolerated - but it was VERY clear that there were times that were 'for adults, shut up and keep your head down' and times that were more child-centric.
Long term - mm, I know how to eat politely at any kind of dinner table and have no urge to run off to dance floors or stand up and shout etc.
On the other hand it took around 20 years of hard work to learn how to be involved in a conversation without fearing humiliation for having said the 'wrong thing'...
