Nasty ass kid in Petsmart!

Today my daughter wanted to go to Petsmart to see the animals. We walked over to where they keep the cats that's for adoption and we hear some really bad coughing coming from somewhere, we look to our right and see a kid that appears to be maybe 10-12 years old sitting on the floor, he sounds like he's coughing up a lung, his cough was terrible and as I was glancing over there he was coughing and spitting into his hand and throwing it all over the items in front of him. Omg, he almost made me puke. I quickly got away from that area because we aren't trying to catch whatever that nasty ass kid had. It was so disgusting. I didn't see his parents anywhere. Now I'm sitting here wondering if we got his germs. Smh. He was a little ways after from us, maybe 10-12 feet from us but still. Paranoia has kicked in y'all. Ugh...
