What are your feelings on someone that's constantly late?

If this is a frequent problem already then you probably want to drop them because the more serious a relationship gets the more important being able to coordinate becomes. These kind of flaky, inconsiderate behaviors become much bigger, ‘disrespect and screwing up things going on in your life/lives’ problems.

On the off chance this isn’t a frequent thing then I wouldn’t stress about it. It sounds like he invited you out to also join in celebrating his good news, but you declined. Part of having a good relationship is being able to join in the good vibes of celebrating each other’s wins. Again, based on the possibility that he doesn’t do this a lot, if you declined going ‘ because it’s the principle of the thing‘ that he had plans with you then change them, it might be worth looking inward at your own rigidity.

Your anger is justified. He’s not a teenager anymore to act so irresponsibly. What he did was v disrespectful. You should discuss it with him…tell him he should have called you and asked you to come join in his celebration.

Everyone is late once in a while. But those that are always late are rude.
It shows a complete lack of respect for you and your time

If this is a romantic connection drop him because hes showing big time signs of disrespect of your time and not really caring what you have going on.

If this is a friend you need to be extremely firm and don't hesitate to cancel if hes taking too long tell him you have something else you have to do.

I do not like that one bit. My time is worth same as yours and I was early.

I tell these people that the event is 30-45 minutes earlier than it actually is. Sometimes I tell them it's an hour earlier. You shouldn't have to do that but it's a useful thing to do if you're dealing with someone who tends to always run late.

Like the others are saying....it's a sign of disregard for your time and it's disrespectful.

It depends on what kind of person they are overall and how it affects me personally but I don't like it. If it happens regularly, they are clearly unreliable.

Definitely another red flag.....

He doesn't respect your time and he doesn't respect your effort (the food).

Sounds like drug issues.

Done ...so done

Geez. He doesn't value your time. I'd be pissed, too.
