That's NOT what I asked for....

I'm in a particularly irritable mood.  Today when paying for my lunch, I asked the cashier to add a Diet Coke to my order, and pointed to the fridge stocked with soda cans.  On my way out, I went to grab my soda.

But there was only caffiene-free Diet Coke.  When I asked about it, I was told they were out of Diet Coke.  I looked at the options - Coca-Cola and Sprite Zero.  Neither would do.  I want the caffeine of the Coca-Cola and the sugar-free, no calories of the Sprite Zero in my cold, lunchtime fizzy drink.

I left quite grouchy with a Sprite Zero.  I really shouldn't be this annoyed.
