I tend to worry about the wafer thin statement, I mean how thin is a wafer? Surely it should be called thinly sliced or even sliced thinly? Civilisations have tumbled and crumbled because questions like this have not been addressed.
More to the point – what’s the point of wafer thin?
If you can read a newspaper though it, it is too thin to provide a tasty sandwich filling so you have to double/triple the thing… why not just make it thicker?
Now THAT is a very valid point. It has irritated me greatly for years.
'Wafer thin' simply gets people to use more.
Instead of using one normal thickness slice, they put several thin slices on which actually equates to more than the single 'normal' amount.
The same applies to 'Snack size' sweets, you end up eating 3 little Mars bars 'because they look small', which is more than one regular bar.
The proletariat consists mainly of suckers for such tricks.
