Customers who ask for things vaguely

Actual encounter I had with a customer who stopped me on a pick run Saturday.

Customer: "Where's your chocolate?" (No excuse me, no sorry to interrupt; nothing)

Me: "Chocolate, like candy bars? Baking chocolate?"

Customer: "The kind you drink."

Me: "Oh, hot chocolate."

Customer: "Yeah, that's it."

Me (slowly pointing behind him): "It's right behind you on the coffee aisle."

Customer: \*turns and walks off\*

Me (continuing on my way): "Why didn't you just start with 'hot chocolate?'"

What's something a customer has asked you for help finding in a vague way where they clearly knew what they were looking for and could have just asked for it by name instead of playing guessing games?
