This is pretty much the worst thing you can do to me... whether it is making me late or showing up to meet me late.
Growing up I was always late and probably 99% of the time it wasn't my fault. I know mom and dad had six kids to get ready and out the door and I of course forgive them. And in high school it was always my sister making me late. We are opposites.
I vowed that when I was on my own I would always be on time... even after having kids. If you know me you know that I show up on time. It's important to me.
Well not because I'm bitter from when I was growing up. I'm not. It's because I believe it is about respect. If you tell someone that you will meet them at a certain time then you should use some good time management, plan your day appropriately and show up on time. I don't want to waste twenty minutes waiting for you. That is twenty minutes I could have used doing something else. Twenty minutes I will never get back. You don't like having to wait for people... don't make them wait for you.
One time a friend told me that she would meet me somewhere at a certain time. She showed up about a half hour late. She came in all apologizing because "I was on the phone with a friend and thought it would be really rude to tell her I had to go." No joke. So she thought it would be rude to end a conversation but it wouldn't be rude to let me wait for a half hour!? She was a habitually late person anyways but I told her next time she shows up late I won't be waiting for her. Some people thought that was rude. I don't.
I can't get that wasted time back.
If you were always late for your job you would probably eventually get fired. Perhaps I need to start "firing" people.
