“Guess how much Office Depot [1] wants for a 10′ cross-over cable?”
“Oh … maybe $20?”
“Try $26.99. That's insane! Home Depot [2] sells them for around $7.00.”
“So why aren't you at Home Depot then?”
“They ran out.”
“Ah.”
“But $26.99! That's insane! I realize they have to make money, and while I can make my own it's more a convenience factor, but $27?”
“See, Office Depot expects you to buy the cables and expense it to a company, so you aren't spending your money, but Other People's Money™.”
“But $80 for a few cables?”
“Other People's Money™, man.”
