Tesco or Safeway
One of my friends insists on referring to Tesco as Safeways. "Safeways tonight, is it?" he'll say, only to aware that there is only Tesco in my wee toon.
I used to correct him, but eventually I capitulated and now I respond, "Safeway it is, indeed."
You'll have noticed that my concession goes only as far a singular Safeway. You'll never find me descending to plural depths.
