The Irrelevant Lunch Companion

Hello. Today I had lunch with a dear friend. I was the first to arrive at the restaurant. My lunch companion didn't arrive until 15 minutes after our agreed-upon time. That was fine with me, but it got me thinking.
Because my lunch companion is relevant, it was irrelevant what time she came to the restaurant. I was going to wait, and even eat alone, no matter what time she came.
On the other hand, I'm irrelevant, so it's relevant when I arrive to the restaurant. If I can 15+ minutes after our agreed-upon time, my relevant friend would be entirely justified in leaving without waiting for me. After all, she has relevant things to do with her day. I have only irrelevant things to do with my day.
Is this fair? Of course it is! So be on time, irrelevant people!

Regards,
Irrelevant
