Instead of going out, maybe they should spend some quality time at home with their kids.
My parents took us to nice restaurants, but we were not allowed to act up. It can be done, but I see people who are just so self absorbed they don't think about anyone else.
We rarely go out, my husband is hard of hearing and it's just not enjoyable anymore. With or without little ones.
Restaurants are so loud too, which makes it worse if you are hard of hearing. And some parents are self absorbed I completely agree. Some people get drunk and laugh & talk decibels above what is comfortable.
I think it is the behavior that is objectionable not the age. But I wouldn’t want to go anywhere we were unwelcome. Restaurants can chose dress code, age code etc. with no complaint from me. Just as I think bakers & caterers should be comfortable with the events they are working for/at not compelled. I had no trouble finding upscale places and if some few were unavailable for our family it was not a problem to me. I really can’t think of anywhere I wanted to go (after checking the menu) that we weren’t welcome.
