When you weigh a bag of spuds at Walmart...
went shopping tonight with my Son, told him to grab a bag of spuds. He asked 5lb, 8lb or 10lb? Then he proceeded to weigh them to see if the package was accurate. I'm pretty anal when it comes to many things but I never would have thought about doing that - well he found out that the bags were off and not by a little either! Some by 2lb while others off by 5lb! Wow
BTW - he varified it against a mechnical scale as well that was located by the greens
