But it's just a bitcoin address. All you need to do is go to an exchange (or a wallet), click withdraw enter the public key of the other person, type in the amount and you're done.

Dropbox is also silly. It's just rsync with a UI, just spin up a command-line and transfer all your fi-... Wait a minute. This is what you meant! ;-)

I'd love to hear a version where a chef would talk about food this way or some other field that I know next to nothing about.

This uses the Lightning Network, which requires an invoice (unless the node has keysend payments enabled, but most end users don't run their own node). It's not the same as a Bitcoin address, and address re-use is a dirty habit anyway.
