So guess who was replacing the nearly emptied coffee
container with a can of coffee, same brand same weight?

So this person inadvertently got the lids mixed up and
the lid of one was too small to fit on the other and the
lid of the other sat loose on the one.

That was an indication that the diameters of
the two cans differed, altering their volume.

Further investigation led me to realize one
of the cans was also a tiny little bit taller
than the smaller, altering its volume.

Next time around I’m gonna weigh the
can before I open it, just to see….
