Dumb people with HUGE dogs!

OK so my job today was floor leader, so just need to direct traffic and keep overall moral up. So this guy comes in the store and if i judge people by looks, then well I would have thought he was homeless. Well he decided that it was a good idea to bring a HUGE dog into the Sprint Store. Dirty harry dog, well there are several kids in the store, i swear the oldest couldn't have been 7, and there were about 10 kids or so in the store. Hello sir the dog is bigger than ALL of the kids in the store. So  I tell him if his dog is not a service dog he was going to have to leave it out side. He gets all defensive of course and says well no one has said anything before. And that his dog was a service dog. I tell him that will out the dog being a certified Service Dog he would need to take it out side, and i would be more than happy to hold his dog while he makes his payment.

Question.... Would you let your kid around this dog face?
