When did the man get the shirt? [originaltext]MB I’d like to return this shirt.

MB I’d like to return this shirt. I bought it here yesterday; here’s my receipt.
WB May I ask what’s the problem with it, sir?
MB It has a hole in it. I haven’t worn It, but I found a hole — here, see? So I’d like to exchange it for another just like it.
WB No problem, sir. If you want to exchange it, leave it here and when you find one you’d like in its place, let me know and I can process the transaction.
