I was wandering around Boots looking for sunscreen. All I wanted was a simple cream to slap on my face while out with the dogs.

I don’t know anything about cleansing, hydrating or moisturising, I’m very wary of that stuff since Mrs B bought me a facewash with grit in it. Can you believe that? I felt like I’d been doused with a sand blaster.

So, here I am drifting down the aisle in Boots when I spot a tube of SP15, which sounds good to me (whatever it is?). I take it to the till to pay.

"We have a three for two offer at the moment," said the assistant breezily.

I wandered back to the display and selected another two alternatives then returned to the till.

"You do know these two are dearer then your initial choice?"

I shrug. "As the three for two relates to the most expensive item you may want to reconsider your initial selection as that is significantly cheaper."

"So, what should I swap it for then?" I asked, totally confused.

"You may as well have another tube of the expensive one."

I meander back wearily to make the exchange. I now have three (expensive) skin protectors.

‘That will be £94," said the assistant.

"NINETY FOUR POUNDS!"

"Sorry, not you. That bill is for these ladies," she said smiling at the two women at the counter.

I somehow managed to recover without a defibrillator.

"Do you have a Boots card?" she asked.

I shook my head, anxious to grab my purchase and leave.

"You can use my card," said the £94 lady.

"No thanks, I’ll just pay and go," I said desperate to make my getaway.

" Did you buy any skin serum?" asked Mrs B when I eventually made it home.

"I’m protecting myself from sunburn not snake bites," I rapped, annoyed that one simple tube of sunscreen had dominated my entire morning.

"It would do wonders for those lines on your face."

" I didn’t have any lines before I went for sunscreen."

Mrs B stared at me as if I was a Shar Pei.

"That’s not what I’m seeing."

I didn’t know whether to argue or bite her leg.
