Ugh. I didn't take this "any way" dave. This is just my response to your question. You asked, I responded. Don't be testy.
BTW.. the name of the series is High Maintenance.

I don't find any of these characters any more unusual than...say... Seinfeld.
So when you ask "are there people really like that"?
..I am perplexed at what "like that" means?

Is someone bringing snacks?
