Can’t Filter Through The Filters

(A customer approaches the counter.)

Customer: “I’m looking for an oil filter; can you help me?”

Me: “No problem. What type are you looking for?”

Customer: “I told you, I need an oil filter.”

Me: “Yes, but what size are you looking for? We have dozens of different types.”

Customer: “Oh, I didn’t know there were different sizes.”

Me: “That’s okay. I’ll just look it up in the catalog. What type of car is it?”

Customer: “It’s a Toyota.”

Me: *getting frustrated* “Okay, what type of Toyota?”

Customer: “I can’t remember.”

Me: “I’m afraid I can’t help you.”
