The great supermarket conspiracy

What is it about supermarkets? Are there many people in the world who can actually walk into a supermarket and walk out with just what they came in for? Every time I'm there I seem to come home with all sorts of random things that I didn't know I need - or even wanted! Yesterday I set out with a mission - I needed four things for a dish I was making - just FOUR things - and that was all I would get. But as soon as I walked into the supermarket I started looking at something else and for five minutes had no idea what I had even come in for cause everything else looked really interesting. But I woke myself up from the trance like state and set about my task like a soldier - and actually managed to pick up just the four things I needed (though I had to fight off the temptation to buy anything else - my mission would be unsuccessful) - and made it all the way to the check out counter. So close. And then I saw it. "Exotic Chocolate" - chocolate with really weird flavourings and fillings - salt, chili, even bacon! And for some reason I saw myself pick up the chili flavoured chocolate (my mission all down the drain) and put it in my pile of things. *sigh* Why do I even want chili flavoured chocolate? I dont really. Especially not one that cost me $8 for a tiny slab. So here I am with my exotic chocolate - yet unopened - just so it can remind me of the great supermarket conspiracy and how I got trapped into it.

As an aside - I forgot to wear my watch and looked around for the time, but couldnt find a clock anywhere. Is that just that one supermarket or do supermarkets like casinos not have clocks either?
