Day 130: The Last Day Of A Long Week

I'm shattered. Absolutely shattered. I've been at work everyday around 6:30am and working till after close. And it's been busy. Very busy. I've been putting together a lot of big orders myself and doing more physical work than usual. Which is not something I usually do, being the lazy bugger I am.

McCombers is busy all weekend, so tonight I'm having a night in with my geeky tv shows and several cups of tea.

In my house I have three coasters, one for me , one for McCombers and one for a guest.

Can you guess which one is which?
