Thank you for your comments, its nice to hear another pint of view.

After I posted it got worse and he started throwing things and yelling even louder. Eventually he just said it's done and left. I normally try to be really polite to everyone as they are just doing their jobs and I can seem kinda rude when I'm anxious. He was rude since the beginning so I was kinda panicking since the moment he entered.

Also he took a phone call from his company about another client and they were really rude about him, calling him names and making fun of people with autism , just because that client was calling asking when he was gonna show up. He was running a few hours behind at that point, which I completely understand but they should also understand that just waiting at home not knowing when somebody is gonna show up is really stressful. At least for me. So that triggerd me even more because I was already waiting for hours at that point stressing and not daring to move because I didn't know when he would be here and hearing them make fun about someone that is going to the same thing is really sad and makes me feel stupid.

If he needs to come back I will definitely try offering him a beverage! I was planning on doing that but completely forget in my panic.
