It depends on the event or situation.

That is one thing where I might try to be more like someone who has brought me down.

If there's a good reason I'm fine with it.. but if they're too late and not call. Then I get cheesed 😊

Just let me know if you’re going to be late and give me an accurate time of arrival. Confession: I was frequently late to dates with my husband. (Only because I had a lot of grooming details to take care of… I’m an extremely hairy and sweaty girl need I say more?). He did get annoyed a lot, , but I’m glad it wasn’t a deal breaker. Generally I’m very punctual.

Around 10 minutes, you get a comment. Over 20 minutes I'll likely be pretty grumpy about it. Over 30 I'll likely just go about my day without them. There are exceptions though - like if they keep me posted and have a good reason - then cool, I'll understand. But if theres a habit of not respecting my time I'm not going to tolerate it for long (yeah - I'd totally stop being friends with someone if it became a habit).

punctuality*

Idk, I've never had a problem with it, but I've never been the organizer of an event.

if you are gonna be more than 10 min late i appreciate the heads up so i can do something else for a bit while i wait for you. i try and do the same thing when i am going to be late, which i don't try to be, but it's not too uncommon for me

I'm nearly always on time when I have a meeting with someone. I don't want to ruin their schedule by being late. I expect the same from the person I have meeting with. However, some people prefer to be fashionably late. I don't usually express the inconvenience that they caused me but inside they make me angry TBH ...

I mean if they said they were coming over to my place at 8 and they show up at 9:17 then I don't care, but if I'm sitting at the bar at Chili's starving, resisting ordering food waiting for you then yeah I will be grouchy for a minute

I'm not a boss/manager of anyone, so I'd say I'm very tolerant

Usually gets a dose of sarcasm before it gets really ugly.

I'm a fucking German! What do you expect!? Plus minus 15 minutes. Out of these bounds you better have a convincing and important excuse!
