I had some interesting responses from my emails to a few contacts in huge businesses about needing the app to enter their private premises....
Put it this way - it was definitely not a 'no will never do that'!....
I think someone needs to go first.... and they would be very brave, but if everyone stacked on quickly afterwards then the people (for whatever self-justified resason) who aren't downloading the app would be encouraged to I'm sure, if they saw their mates out shopping etc and they couldn't....
