Jeweler or Jeweller?
I was puzzled when I saw this sign because I thought the "correct" spelling is "jeweler". I put "correct" in quotes because Merriam-Webster lists two spellings. I suspected that it's a British spelling, so I did a search online, and found a number of sites with it, including the British Jewellers Association.
As I'm typing this, Blogger is pointing out that "jeweller" is a misspelling, and word processing programs agree. I wonder if they do the same with "jeweler" over there.
