Whilst out with friends today, I noticed an interesting sign outside Asda:
Free eye test with every pair of glasses
Or words to that effect.
So, does that mean that you've got to buy the glasses before you get the eye test? What if you buy the wrong ones?
What if, for example, you buy glasses that correct short-sightedness and then have an eye test that concludes that you're actually long-sighted?
Will the staff just point and laugh at you, before calling you a sucker and charging you for the correct pair of glasses?
And, if that happened, would you then have to face the ultimate insult of earning another free eye test, which by now would be of no use to you?
I wonder if the free eye test is transferable. Perhaps, if one person was prepared to be the fall guy, they could get as far as buying two pairs of glasses, then pass the second free eye test on to somebody else; who could then buy the correct glasses the first time around, earn their free eye test and pass it on to somebody else. And so on and so forth.
I think it would work, but we'll come unstuck the second anybody with good vision gets caught up in the loop…
That said, I'm sure a quick poke with a fork could soon fix that.
Otherwise, I've got this nightmare vision of somebody walking into Asda, buying a nice pair of glasses and then having an free eye test that concludes that they had perfect vision all along.
And cue all the gags about hindsight being 20/20.
