LOL, human scales, Jay.
One human Publix scale was pretty accurate - it said I weighed 165, which between my clothes, accessories, and bag, was probably about right.
Another time, I had a Publix scale tell me I weighed 171, when my home scale said 163. I hadn't eaten anything, but I was obviously clothed - and I conducted an experiement (NOT done at Publix, obviously
) - my average pair of jeans plus my studded belt that I always wear and my chain wallet and pins usually weighs 3 pounds
add the shirt and any headwear, and that's probably 2 more - though I was still wondering where those three more pounds after that came from. My girlfriend stepped on the same scale, which told her she was around 5 pounds more than the doc office scale does.
