I'm thinking of cancelling my hair stylist because I was 18 minutes late
Why would you do that? You were the late one, why cancel?
This is the third time I'm doing this.
The third time? Wow, I think you should cancel too. If you cannont get there on time you should call ahead and reschedule.
Nah I'll just go there and cancel. It's no big deal.
It is a big deal when you have been being late for a long time. Can you think about how the hairdresser feels, they reserved a spot for you and you didn't show up. That could have gone to someone who really needed it, and now they won't get paid either.
