(I work in the wine department of a well known grocery chain.)

Customer: “Can you show me where the Charbonnay is?”

Me: “Ah, you mean Chardonnay. It’s right over here.”

(I hand her a bottle.)

Customer: “That’s not Charbonnay. Charbonnay is RED!”

Me: “Oh, sorry. Here you go!”

(I hand her a bottle of Cabernet sauvignon.)

Customer: “That’s more like it!” *waddles off grumbling about how stupid I am*
