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?
