Seen on the way from Basel airport on 3 October 2013: “Alle Pizza’s werden geliefert.”
English grocers are notorious for serving apostrophes with everything. But now the malady has spread to a language that doesn’t even have apostrophes.
(German does use the apostrophe to show that a letter or sound has been omitted.)
In contrast, Dutch actually requires the apostrophe in the rare words that have an “s” plural, usually foreign imports: foto, foto’s.
