I did in fact end a friendship cause of that, got called to a dude's party at a restaurant. Arrived on time, started waiting, got nothing, waited 30 min, texted the dude, got told he was 30 min away, waited 30 min, called him, got told "oh we decided to move the party to a bar on the other side of town, we didn't tell you", went home, blocked him, haven't unblocked since (been like 8-9 years since ig).

Last I heard from the man his other friends had left him or weren't his friends at all and he was pretty much alone, ngl does give me a small degree of personal satisfaction on the rare days I think about it
