Invited two friends round for dinner tonight. Due to another commitment it was always going to be late (arrive half 8 eat at 9) explicitly said this when I was arranging it as I know it’s very late for some people.
Assured me it’s fine.
Got food in inc some naice (fucking expensive) ingredients. Get everything cooking, text at 8:45 asking if they are on their way.
Reply “oh no we were too hungry to had to make our own dinner, we can come round in an hour or two after we’re done.”
I was a bit hacked off so told them not to bother 
Aibu to be pretty seething
