I was lucky enough to eat out a lot as a child (born to older parents who were not changing their lifestyle for kids!) Although mainly lunch time so as not to impact adults enjoying an evening meal. I also think that kn the 90s kids just weren't accepted in restaurants of an evening??
We would always sit quietly and maybe colour or draw. If we were the only people in our local Indian on a Saturday lunch then we would be allowed to play by the water feature (proper 90s) but if anyone else walked in it was straight to our table.
I distinctly remember being in a Chinese restaurant when the kids from another family were running riot and unwrapping all of the chopsticks. I asked my mum why they were being so naughty
(eldest child who always does as she's told!)
I could be silenced by a look from one of my parents. Parents these days don't give a
tit.
