Kwik Kar Lube and Tune

I came by a few minutes before 5 to get an inspection . The guy at the desk took my keys and my insurance and told me they would get me taken care of. My daughter and I hung out in the lobby for a few minutes before walked across the street to get tea. An employee yelled at us from the door something I couldnt hear. I motioned we would be right back and they were pulling my car into the bay. He nodded to me. 
Upon returning not five minutes later, the whole facility has been shut up and my car is sitting in the parking lot. When we come inside the owner, aggravated, gets up thrusts my keys at me says harshly "Here are your keys!" I took them from him and ask him what is going on to which he responds "I told you we are closed. I cant hold four guys here while you go across the street for a drink!" Excuse me? I told him we were told they would do it, had no idea they were closing, it says on the door they close at 6 and it is 5:10. Again, instead of addressing me as a professional, he takes a rude tone with me: "We close at 5 during the winter and 6 in the summer." I realized there would be getting no where with a guy who acted like this. So I just told him the website also says 6 and walked out. I tried to message him on Facebook asking why I would get treated in such a way when I was only trying to frequent his establishment but he has no leg to stand on and wont answer.
