if they have customer from Grindr it's fine but if it's out of sheer laziness I side with hank above, it's arrogance. While 200 is not a lot , it's still plenty enough for anybody to get their ass from the chair and lift it from the floor and thinking otherwise invites bad karma.
I once arranged with popular guy I liked a lot for mid-day meeting , not sure it was 1.5 k or perhaps even 2000. We were supposed to meet at 3pm in front of his , at that time closed, bar. After waiting 30 mins I went my way , only to receive message around 5 pm "sorry , I slept in". it took me 2 or 3 trips before I stepped in his bar again. We talk and drink again but can't bring myself to off him again .
