Recently I made a computer keyboard purchase, simple WFH keyboard and it was only 1 week old.
I went into store to get a refund, the gentleman in the tech area 'tested' it by bashing the keys a few times and pairing it to their in-store laptop. I advised him a key didn't work but he kept bashing that specific key until it worked. Then said, this is general wear and tear, no refund.
I was unhappy as I knew it wasn't a long term solution, so I asked for a refund. He refused and said no way, there is nothing wrong, albeit he bashed the keyboard ...
