I sell fairly high-end custom props. A few months after selling a £250 electronic item to a customer who moved back to the far east, I had this conversation via Facebook.
Client: It’s broken
Me: Well you have a warranty, if you send it back I can have a look for you.
Client: I already opened it, and took it apart to try and fix it.
Me: Well that will have invalidated your warranty as per my terms and conditions. Do you have any electronics or wiring experience?
Me: Can you send it back then?
Client: Well I’m in Malaysia now.
Client: My friend here is looking at it now though. He’s an electronics expert.
Me: Well I’ll try and offer any advice I can.
Client: My friend says he doesn’t know how to take it apart.
Me: *head hits desk*
