Child-friendly establishment not so child-friendly

My Mom, 2 kids and I went to Wimpy in Kenilworth Centre to get something to eat. One of my kids is a 2 year old boy who hardly gets an opportunity to go out because I don't always have money to take them out. Needless to say he was ecstatic so when we went to sit down and he was given a menu, he wanted to have a burger, chips and milkshake. While sitting there and waiting he couldn't contain himself and he started shouting BURGER, the other people in the restaurant started shouting with him and were laughing at the way he was going on and they were egging him on to do it again which he did. The Manager then came to my table and said we need to make him quiet because there are other people in the restaurant. How do you get an excited boy like that to keep quiet? We hit him but that didn't help so we were embarrassed and left without even getting out food. People were telling me oh no man, that's so wrong. We left with 2 starving unhappy kids and what was sad was that my son fell asleep after the ordeal and when he woke up he asked for his burger and milkshake. We are regulars at this Wimpy and spend a lot of my but they've lost a customer now. This left a very bitter taste in mouth.
