(I am scanning a customer’s order when I notice she is buying a $30 lip-gloss that is also being given away with a magazine).

Me: "Miss, if you’d like to buy [magazine] for $7.20, you get this exact lip-gloss free inside."

Customer: "But I don’t want the magazine. I just want the lip-gloss."

Me: "I understand, but even if you give the magazine away, you still get the lip-gloss for $7.20 and save $22.80."

Customer: "Do I look like a charity? I’m not going to give away a $7 magazine. Haven’t you heard of saving money?"

Me: "Well yes, what I’m saying is you can save money by buying the magazine–"

Customer: "Stop trying to rip me off and scan my lip-gloss!"

(I ring up her lip-gloss for $30 and she storms off. The next customer puts the same magazine on the counter.)

Next Customer: "I don’t want it either, but I have half a brain."

Sadly, I know people who are like the first customer. I've checked them out at my job. REALLY makes you wonder about the nation's average intelligence.
