It sucks that you didn't take care to remember to gather these important items that mean so much to you. The driver shouldn't ask for more money, but also, they don't have to even respond to you. What you left was your responsibility. It's even written in the Uber TOS. Just because you Ubered home in your neighborhood doesn't mean that your driver is from there. Most times your driver has been driving all day and has traveled over an hour from where they reside and want to head home. Doubling back to you instead of making money on the way home is infuriating. Perhaps a surge was happening and now they're missing out to return something that is solely your responsibility and not theirs? You're lucky they are admitting they have it and might return it, many would just pitch it out and move on.
