Reminds me of some misadventures I had with the Midwest dialect when I first moved there.
1/
Me [at a restaurant]: "What do you have on tap?"
Waitress [with offended look]: "On tap [top] of what?"
2/
Me [at a store]: "I would like to buy some racks."
Sales woman: "You want to buy some racks?"
Me: "Yes, to put on a wall."
Sales woman: "You want to put racks on your wall?"
Me: "Yes."
This line of discussion goes back and forth several times . . .
Sales woman: "Okay. Why do you want to put racks on your wall?"
Me: "To hold books and other things."
Sales woman: "Oh. You want racks [rhaahcks]. I thought you meant racks [rocks]."
