We’re Not Half Surprised

(We have a table marked 50% off different items. A woman approaches me.)

Customer: “Excuse me. This is regularly $7.00; how much is it on sale for?”

Me: “It’s 50% off; everything on this table is discounted half-off.”

Customer: “So, this is $14.00; how much is this half-off?”

Me: “That would be $7.00.”

Customer: “And what if it’s $10?”

Me: *pause* “Five.”

Customer: “This one is $4, so how much is that?”

Me: *longer pause* “Two.”
