I spent a bit over a week in Italy, and got asked for a green pass (Italy's vax passport) in three types of locations: McDonald's, Starbucks, and the dining are at Rome airport.
The latter was particularly funny as you're still allowed to eat without one. You just have to stand up at tables provided for that purpose, located in tbe same area.
In all three cases the staff said _only_ green pass was accepted. _Not_ proof of vaccination from non-EU countries. Which is supposed to be accepted!
I probably could have convinced the security guard to let me stay with Canadian and maybe US (CDC) "proof" of vaccination. But pretty lol that the staff don't know the rules at an airport.
@verretor Apparently France's scheme for recognizing foreign vaccination _requires_ you to have a return flight booked. I often show up in countries without even having accommodation booked...
It's a huge mess. You know, verifiable creditials and "decentralized" identities. Everyone is rolling up their own system.
