Today, I demonstrated my skills to the girl at the gas station

“Damned thing just won’t scan” as she swipes my egg sandwich over and over again
“I have that skill, that gift. I can find the one useless barcode in the store”
“But it looks fine! Why won’t it scan?”
“because I have skills. Fear me”

Usually, that skill is devoted to finding the one package of Stayfree Maxi Pads which won’t scan at Jewel “Can I get a price on some Maxi’s for the big guy with a beard? ”

What mad skillz do you have?
