I had a very successful business selling knives in Bulgaria a few years ago. One day a guy calls me with an order.
Client: I want that knife.
Me: Awesome. Are you from my city, or want it sent by courier?
Client: I want it sent here: [gives me address]
Me: Okay, I’ll send it right away.
Client: But, can I pay with tires? I have a few very good used winter tires from a bus, I don’t need them, so I can give them to you for free in exchange for the knife. What do you think?
Me: Hahaha, good joke.
Client: No, it’s not a joke. Sorry. Can you please send me the knife, I will send the tires.
Me: I don’t need tires. Why would I need used bus tires?
Client: Okay… but if you reconsider, I’m here.
