You can just make up some e-mail as, without internet, you couldn’t verify it. Also one of the rare cases where VPN directly improve your privacy.
At nearly any gas station in NRW, Germany it’s this way as well and I absolutely hate it.
It sounds to me like they are developing some tools to help map things inside the store. So they can give you directions to things you are looking for maybe. Also with this information they could do something similar to those Amazon stores where you just pick things up and walk out and it charges you automatically.
Not saying you all want to share the info with them. It is invasive. But as an engineer I can see so many cool features I could build with this information.
Well that’s just plain invasive. I’ll make sure to take myself off of their network next time I’m there.
