The race management should be setting and monitoring what teams can do, just as was done at the TdF. I think serious questions need to be asked of the Giro organizers. From what I am reading today I'd say what "bubble" ? The Tour just provided the blueprint but it seems the Giro didn't monitor the Tour and learn.Shared buffets (if that was the case) is as much a team management failure as a race management failure. Maybe more so. Why are you letting your riders do that ? Why are you (as the hotel customer) not insisting on separated dining ?
