Oh Dear, I am on the fence on this. Children are small people, people being the operative word here. You shouldn’t discriminate on age as well as race, gender etc etc. Eating out is a valuable experience not only for adults, but for children too. Part of being a society is being supportive of children who are a part of society. As long as they are well behaved (just like adults) and only linger a short amount of time (have consideration for the business needs of the vendor just like their parents) then they should be welcome. Minimum spend is a slippery road... I understand the reason, but dread the eventual outcome.
Having a narcissistic parent is much more common than I thought. According to other forums they are everywhere. My mother is the same............which is why the stories fascinate me. I was 30-35 before I realised it isn’t my job to smooth over the issues but to support my siblings and how we feel when targeted. To validate especially my brothers experiences who I think has suffered more than any of us.
