Do I have a right to be kind of pissed off at my autistic co worker?

I work for a commercial cleaning company. I'm 30, and my co worker is 37. He had pretty sever autism, but he can work, and live by himself. Well, we clock in and out on our phones using an app. Yesterday his app was giving him trouble so I just clocked in and out for him, and I both. Before that, he was trying to get it to work on his phone, then he called our boss to tell her the app wasn't working.

He kept cussing, and a couple of times it seemed like he was cussing at our boss. He kept going "fuck you" but he was talking to his phone. My boss had to tell him 5 times just to stop messing with the app, and to just get to work. So he has a friend who he's told numerous times to not call him while he's working. Well, as he was on the phone with our boss, his friend of course calls. So he hangs up with our boss. We aren't even in the building we are supposed to clean yet. We walk in. I walk to the other end of the buildings, and I noticed there was still someone working in their office, so I walk over to my co worker and tell him not to cuss because someone is here.

He does a pretty good job not cussing, but he called his friend back, and they were talking for like 10 mins. After 10 mins his friends voice gets hard to hear. I think she was outside or something. He raised his voice, and was like "I can't understand you!" He hangs up, and calls her for like 20 mins. We havnt even started working yet. Well I have but he hasn't. It was embarrassing because the worker (who we know pretty well) walks up, and goes "are you guys working today"? She said that because we havnt even got to work yet. Finally he calms down, and gets working, but he wouldn't shut up about his phone. I stayed calm the whole time, and kept telling him that it's gonna be okay. Anyways, I was pissed because a job that should have taken us a half hour takes us over an hour, because he wouldn't stop fucking with his phone. So do I have a right to be kind of mad at him? I know he has autism, but still...
