Where does this conversation take place?

M: Good morning.(47,49)I bought this water faucet from your store just a week ago, and(48)it is already starting to get discolored. I want a refund. Here is the receipt.
W: I’m sorry, but this receipt says that this product was on sale. We don’t do refunds on sale items. Would an exchange for a new one be okay?
M: But I want a refund. I heard your store gives refunds on any items up to 10 days after purchase.
W: I would like to help you sir, but you have to understand our return policy. An exchange for a new one is the best I can offer you.
