You Might Have To Use More Than Ten Percent Of Your Brain Cells

My partner bought a pair of new walking boots but they’re a bit on the small size so I take them — with the receipt — back to the shop to get them swapped for the next size up.

Clerk: “Yes, that’s no problem but there might be some extra to pay.”

I try to remember if they were on sale.

Clerk: “Because you used an armed forces discount on these and the trainers you bought, there’ll be a lower amount of discount on just these.”

I must look blank because she continues to try and explain.

Clerk: “See here, you bought these at £42 and a pair of trainers at £35, so you got a £7.70 armed forces discount. Because you’re only returning the boots, it’ll be less discount so you might have to pay more than £42.”

I realise that trying to explain that 10% is always going to be 10% is probably a waste of my time, oxygen, and patience.

Me: “That’s fine. Just ring it up and see how it comes out.”

The clerk rings up the exchange.

Clerk: “Oh… it came out the same.”

I smiled, took the receipt, and left before my remaining brain cells could commit suicide. The kicker is that I actually have mild dyscalculia and struggle with basic maths, but even I know that 10% is, in fact, always 10%.
