In Italy the big issue of the moment is people overcrowding the bars zone. You see every day photos of zones where usually there was nightlife, which are completely crowded like if there was no pandemic around.
It's a double edged sword because on one hand, bars and restaurants DID open, and they are required to inforce social distancing, sanitizing, etc..., but on the other hand, if you allow people to go outside, they will just do it; nobody will "sacrifice" themselves and say "well, it's better to sit tight for a while", everyone will go out expecting somebody else to stay at home instead. I can't imagine anybody going into "Nightlife Trendy Street", seeing many people around, and go "oh shit it's better we go home". Once they've decided to have a night out, they will.
