Children no longer allowed inside kfc

I've just been to the douglasdale branch and informed that children are not permitted inside the shop, not inner of the 5 staff members could give me a reason, I'm not going to let my 6 year old child stand outside unattended in a busy parking lot, this will be my last trip to KFC, there is also no sign outside telling me what age children will be allowed in, I'll come back when he's 18.. utterly disgusted when these news rules are unforced by three member of staff who sprays hands.
