How long is the 'ish' cushion really?

I had this debate the other day. I need your guys take on it.

I had this debate the other day. I need your guys take on it. When somebody says they're arriving, say they're going to pick you up around like 7, what is the time frame of ish? They better not pick me up before seven. Ish is only after. It's only after. And I'd say it's, I'd say it's 15 to 20 minutes after 7. I don't mind that. That's what I would say. At what point does it get egregious? Say for example, I'm going to pick you up at 7ish, and then you expect to be ready at 7 but say show up at like 7:30, 5:40, way too late. You're like, dude, where are you? If you're going to pick someone up at 7:30, you're going to say 7:30. 7:30. Ish would be like you got up until 8 or no. Yeah, right. I would say like, I'd say probably got, probably got till 7:50. So is the ish cushion maxing out at 20 minutes? I. In my, in my book, ish cushion max maxes out at 20.
