I always like to go all OCD on mathematics in shops … especially when they fail to honour the special prices at the checkout (our local SuperValu is, sad to say, a prime offender here). Even if it may be just a few cents, there’s me going “No!” Usually followed by a puzzled look, than an explanation, than a very dubious glance, than my admonition to “Go and check for yourself …”
That, usually, is either followed by swift action or, in too many cases, a long leisurely stroll through the whole store (as if they suddenly moved the grocery section without informing anyone), a discussion with any manager unlucky to be there (“He says that is a special, but the machine did not take it, what shall I do?”), a search for that magic key that allows to correct the checkout till, a process of fumbling and trying to remember what to do, finally a correction and a grunted half-apology (which segues perfectly into an unspoken accusation that I, again, had to be a spanner in the works).
Well … get your act together and I will be out of the shop like diarrhoea out of a duck. Promise. Without the mess.
Anyway – here’s a mathematical Wunderkind in action at Heatons. The sign says “Sale – up to 50% off!” Do the maths. And then have a wild guess why I did not complain …
