I'm going to be late for my ride  making my driver late for lunch plans he had for a friend
Is there any reason you're going to be late?
There is none, it's no big deal for me.
Thinking your time is more important than what they could be doing is wrong. Being late tells others a lot about you, your integrity, and your respect for other people, and none of it is good.
Okay, I'm not going to make them wait for me.
It's good that you changed your mind. If you're late you can find other means to commute to wherever you're going.
