On Norwich market there are several stalls selling fruit and vegetables. One in particular has me grinding my teeth. Their large price list is something like this:-

cauli's
spud's
cherrie's
and the best one -
asparagu's

As a retired teacher, I itch to give them detention and make them write out the whole thing ten times, with NO apostrophes.
But they always greet us warmly, and are lovely to my husband, picking out the best Scotch bonnets for him.
