If you don’t take AZ and NV with you, you will get your Colorado River water cut off and lose a lot of farming power. That might even require UT. Unless it’s only Northern California included, in which case you still lose that agriculture, and possible land based trade lines to Mexico. It’s not a clean and pretty separation.

Walmart has Spark which is a delivery network they control that’s similar to door dash but AFAIK doesn’t require any logos on the vehicles.

When I worked for a bank call center the first question before initiating the dispute/chargeback process is “did you attempt to resolve this with the merchant first?” It is a requirement for doing the dispute. OP needs to clearly say yes, and they prevent it by not letting me speak to a human.

OP should also file a police report immediately. They won’t care, but at least the store can’t accuse OP of not following properof procedures.

Download the Phyphox app to access your phones raw sensor data. Very much like a tricorder.

Check out the app Phyphox, it uses all your existing sensors and probably surpasses tricorders in several ways while, of course, lacking in a few others.
