It seems to me that this idea is a race to the bottom. If people continue to give up first level information (name, address, etc) it devalues it because that info becomes commonplace and widely distributed. So what happens then -- dig deeper into your life? Does the 2019 version of this cafe want complete access to your phone / laptop? What about the 2020 version?

It's certainly not a one off as apparently they have limits for per hour and per day.
