"I wish to make a return."
"We can help you with that. What are you returning?"
"2020"
"Oh boy, there's been a run on them. Can I ask the reason you're returning it?"
"It's defective"
"Yeah, we're getting that a lot. Do you have your receipt?"
"Uh, no. Can I do an even trade?"
"I'm sorry, 2020 has been recalled, so we're out of stock."
"Then if it's been recalled, can't I just get my money back?"
"Sorry, not without a receipt"
