Had to say more than once a day. Literally once an hour. I manufacture foam bead material and have to stand on the material scale while I hang a 4x4x5 foot bag to fill every hour.
Good thing is, it reads 3 lb. high, so when I get home, take off the 3 pounds of clothing and pocket stuff, and step on my scale at home, I've lost 6 pounds on the half hour drive, LOL.
