Customer: “I’d like a cartridge for my printer, please.”

Me: “Yes, of course. Which one would you like?”

Customer: “The one for my printer.”

Me: “Which printer is it?”

Customer: “The one that sits on my desk.”

Me: “What type of printer is it?”

Customer: “The one that sits on my desk.”

Me: “Do you know the type or the cartridge number? Did you bring the cartridge with you?”

Customer: “No. It sits on my desk. You must know which one it is!”

Me: “I’m sorry, I don’t. All of these cartridges are for different types of printers, and I’ll need to know what type of printer you have.”

Customer: “It sits at my desk! You have to know! I bought it here last year!”

Me: “We sell hundreds of printers each year. Is it HP, Lexmark, or Epson?”

Customer: “Look, I bought it here! I need a cartridge and I want it for the printer that sits on my desk!”

Me: “I’m very sorry, ma’am, but unless you know the kind of printer you have, I can’t help you.”

Customer: “What horrible service! I’m never coming back here again!” *storms out*
