Don't you just hate waiting for people

The plumber was suppose to change my bathroom faucet
yesterday  but he never showed up. He calls me at 7:30
last night to tell me he'd be here at 9 AM. At 10 AM  I
call him and there was no answer so I left a message.
It is now 1:30 PM and he still hasn't showed up. I'm tired
of waiting for him so I'm going to do my groceries now.
You should not make people wait if you're not planning on
showing  up.
