Haha. I often say: "Most people are fucking stupid".

I thought you were just of the random dudes that spat out a negative opinion, but you actually had knowledge to back it up, good on you!

You know the stupid sayings when a soccer team loses 1-2 for instance and one supporter says to the next, haha - I knew your team would lose, how fucking stupid are you! I don't condone that kind of sillyness.

However, at the moment, you're right in everything you say. But at the same time, some people will always not go for the best bargains. You will find people go on saturday evenings to buy expensive pizza on a gas station, while they could've bought it for almost half the price during the week in a normal super market. That's also pretty stupid, but people still do it.
