At the petrol station today, I was filling my car and a local 'VIP' (imagine big, ld, very fat and tweedy landowner businessman type) drove in behind me, stopped, jumped out and stood watching me.
My car is a swine to put petrol in, the pump is forever stopping so you have to continually let go of the trigger and start again.
He started tapping his pocket, looking at his watch; glaring at me and sighing and sighing.
Of course, when I went in to pay there was a queue and then when it was my turn the cashier had to change the till roll!
When I finally came out he was red-faced and shouted "Come on my dear, some of us have better things to do than waste time waiting you know"
Made me see 
I asked him "Oh, sorry are you in a hurry then?"
And when he of course said yes, I - to my shame - said "Tough!"
