That old saying had a clear meaning, right?
Until recently, that is.
For the first time in my life, I opened Bumble Bee sardine tins — 3 over the course of a month — and in all three found, upon peeling back the finger-cutter, that I could see the bottom of the tin.
Yes, the sardines had been layered somewhat diagonally, so they could get fewer fish into the tin.
It gives a weight, but naturally I don’t have any old tins to compare with, to see if the weight is diminished. If it’s not, I guess I shouldn’t complain.
Yet here I am.

The only times I’ve seen the bottom of tuna can was after I finished eating.
