I hate that products sometimes seem to come in containers designed not for convenience and efficiency, but presumably to make us buy more sooner. A container of seasoned salt may be mostly clear plastic, but down near the bottom the label goes all the way around so you can't tell when it's nearly empty, other than by estimating how heavy it is.
The worst examples are those deodorant sticks that become top-heavy as you use them up and also have rounded lids or caps so you can't store them upside down. When the product is nearly gone it'll topple over if a fly sneezes on it.
