I once went to buy a watch battery. They came in a two pack,
I only wanted one. The sales girl said to save one by wrapping
it in tinfoil and putting it in the fridge!!! Where in the world did
she get that?

Well, doesn't one same unneeded food by wrapping it in foil and sticking it
in the refrigerator?

Ignoring the fact that the foil would have shorted the cell... This is
actually a perfectly good idea if you can seal the cell in a moisture-proof
package (so it doesn't dry out in the refrigerator's low humidity).
