It seems, that most people are literally incapable of practical thinking.

I enter a bedsheets shop, and take a deep look into the shopkeepers eyes. I made sure she is paying full attention. So: I am learning to sew, and I need the cheapest fabric you have...
> We do not sell fabrics.

I enter a fabric shop. I inspect one piece of fabric. Nice, soft, not scratchy...
> Obviously it's not scratchy. It's made for curtains...

I would joke, that people need labels on possible uses so fucking much, that they need a "coffee milk" in order to add milk to their coffees. But jokes on me, because a coffee milk already fucking exists.
