Tardy slips

So, I have a little quirk that requires that I arrive every place on time, or even early - I just cannot be late. It's a very helpful quirk in most circumstances, like work, movies, etc. However, at other times, it leaves me waiting for the other person (especially at parties, dinners, etc.). Well, I was reminded that I need to reign it in after I was left sitting and waiting for people 3 times in the last 3 days, totalling about 90 minutes of waiting. Yeah, 90 minutes of waiting. Lots of waiting and nothing to do...
