I’ll bet my left nut that you don’t have a male USB-A to female USB-C adapter that can support fast charging. So you’ll still end up ordering one from Amazon - a local store is unlikely to carry one.

USB-A to USB-C is the current standard. I am convinced they include a USB-C to USB-C cable because most people don’t have those chargers, so they’ll be more likely to order one with their phone.

In what non private residence enclosed places are you alone? I can’t think of any. Are you talking about hotels or… Because yea that would be ridiculous. But also, since you’re alone it’s not like anyone can enforce the mandate or even know you’re not following it.
