walmart scale.

last year about Dec 2019, I went to Walmart at 120 st &72 ave, surrey, the walmart scale is not 0, when it is empty. the customer in front me, told the staff that problem, so the staff adjusted it to 0. (I did not pay attention, but, I felt lucky, somebody found it). I did not mean Crystal mall get the scale wrong, usually, in Canada, it is really unworthly to change the scale, because the penalty it high. I trusted all scales in Canada!
