A shred of toilet paper

Why don’t the makers of commerical rolls of toilet paper actually test them out in the aparatus for which they are intended to be used in? I refer specifically to being able to unroll a length of toilet paper from a near full roll of paper in the dispenser which is impossible because the roll is so heavy that the act of pulling on the end of the roll causes only the little bit of paper helf between your thumb and finger (or however you do it) to be torn off. ARRRGH! I need to work in product testing I can see!
