Well you said you don’t like when people give you hints and want direct communication, yet you expected this guy to get a hint. He’s not a mind reader. He possibly didn’t know it hurt your feelings. When directly asked, he stopped.

As about trying not to laugh, sometimes it’s hard to control, it could be an anxious reaction to embarrassment and being called out. It’s not abnormal to react in that manner.

He possibly didn’t know he was being rude and disrespectful. You shared a story, never asked him not to comment, maybe he just went along. Maybe he thinks he is bonding in that way, maybe he himself was kicked out drunk and he could relate and don’t mean disrespect.

It seems that you assign thoughts and feelings and character traits to people quite a bit. He just wants money (honestly that’s why most people work-to pay bills), he is disrespectful etc
