Who counts?

Here's a silly thought that popped into my head. Does anyone actually count? I mean like when you buy a roll of paper towels and it says 90, two-ply sheets. Has anyone ever counted the sheets? How about over-the-counter pills? The bottle says 100 pills but has anyone actually opened the bottle and counted them?

Companies could be ripping off Joe Consumer! Just think, if the company that supplied America with the 100 pill bottle, actually put only 99 pills in... One-hundred bottles later, they'd have an extra 100 pills. That would be enough to fill one more bottle! (with 1 pill to spare.)

Makes you wonder, doesn't it.
