If you were coming here to pick up some glasses, you might wonder if you are seeing ddoouubbllee. The first thing you notice is the overabundance of “e”s; the second thing is that, at least they spelled it consistently on every sign they have.
A variant of “shop,” “shoppe” is derived from Middle English. My idea of a “shoppe” is one that sells knick-knacks and tea sets and antiques. Not prescriptions. In any event, they went for the extra “e”, which makes this word look like “shop-pee”, bringing to mind another set of images.
