Upselling

I went into a petrol station shop the other day to buy a sandwich and some water as I’d had no lunch. I approached the till counter with my choices, a BLT and a bottle of sparkling water.
The cashier gentleman behind the counter looked at my purchases and said, “No fuel.”
I wondered what that had to do with me as I am not responsible for ordering the company’s fuel stock, but then I realised he was actually asking if I had bought any fuel for my vehicle.
“No,” I said, “just these.”
He then scanned the items and said, “That’s five pounds twenty-four.”
I pulled out my debit card to pay but then he said, “If you get a meal deal it’s cheaper.”
“Okay. What’s a meal deal?” I asked.
“You can add a bag of crisps or a bar of chocolate.”
“I don’t eat crisps,” I replied. “But, uh … the chocolate … what, any chocolate at all?”
The cashier extended a finger indicating a nearby selection of chocolate products. “Just from them two rows,” he said.
Fair enough, I thought. Sounds like a bargain. I scanned the rows and picked out a Mars Bar which I placed on the counter next to the sandwich and the bottle of water.”
The cashier scanned it and said, “That’s five pounds forty-nine.”
I looked at him. “Sorry?”
“Five pounds forty-nine,” he said again, only a little louder as if I was hard of hearing.
“Sorry, I meant that’s twenty-five pence more. You said the meal deal was cheaper.”
“It is,” he said.
“No, it’s not cheaper. It’s twenty-five pence more expensive.”
“It’s a better deal. You get a Mars Bar with this deal,” the cashier said, as if I was stupid."
“This deal? But we weren’t doing a deal in the first place. I came in to buy a sandwich and bottle of water. I didn’t look for, nor ask for, a Mars Bar. So the purchases I actually wanted were less expensive than what they now are with a Mars Bar. So, therefore your meal deal is not flipping cheaper at all. Definitely not cheaper than the two items I was going to pay for originally.”
“But the meal deal is better,” the cashier said.
“Better than what?” I queried, but without waiting for a response continued, “It’s not better for me because I wasn’t looking to buy a Mars Bar in the first place. Granted it might be better labelled a ‘Meal Deal’ than if I bought all three items individually, but I wasn’t doing that so it ain’t cheaper. And anyway you never said, the meal deal was better. You said 'cheaper' which, because it costs me more money, like five pounds forty-nine pence instead of five pounds and twenty-five pence, it is clearly not the case. That's simple maths. You with me?”
A queue was forming. The cashier looked past me and then focussed on my purchases. “So you don’t want the Mars Bar?” he said.
I watched as he moved it to one side. I hesitated and then said, “Yes. I do.” I was invested in it now. I like chocolate. It wasn’t about the cost - it was only twenty-five pence. “I’ll take it. But it isn’t cheaper.”
The cashier shrugged and scanned the additional item. “You wanna receipt?”
No! I don’t want a bloody receipt was my immediate thought, but I just said, “No, thank you.”
