I don't see the problem with it personally (I am a dad btw). We have a local cafe that has the same policy, some people just don't want to be around kids when they go for a meal/coffee etc, surely that's their choice?
Ditto this. There are plenty of family oriented restaurants around, I don't see the issue?
we can't ban people on skin colour, gender or sexuality but it seems age is ok?
There are plenty of circumstances where it's acceptable to discriminate based on age, or do you think kids should be allowed into nightclubs, to buy alcohol, drive, and get credit cards?
The difference is that you make a choice to have kids, you don't get a choice whether youre black, gay, disabled or ginger!
