Late, Tardy, Behind Schedule, Running Late

I hate when people are late, I feel so embarrassed when I'm late for other people or meetings... I like punctuality... I'm a programmer, I hate running late on projects...

So right now, Sunday afternoon, one of my precious days off, and I'm sat idle waiting on other people...whom have neither text nor called to say they're running late.. and you know what, I bet money when they get here they'll not even apologise.
