Since so many people are talking about their experience/situation I thought that mine could interest some of you.
For those that don't know I live in Portugal, in the Porto area. We gradually entered in lock down for two weeks, and are formally on "state of emergency" for a week now.
This means that most things that attract people are closed. Shops of non-essential things (clothes, for example, are considered non-essential now, but you can always buy some in bigger supermarkets), restaurants (except take-away), cafes, schools, universities, libraries, museums, parks, etc... Public services are reduced to a minimum, basically answering urgent situations. Public transportation works but has limits in occupation (buses carry just 10 people, to allow proper distance) and are free (at least in my area).
Factories can work, as long as they implement security measures (distances and/or protective gear). Car repair and other similar "support" services also work, but most only with a previous schedule call. People are strongly encouraged to work from home if they can (that's what I do).
Supermarkets, bakeries, fruit sellers and everything related to food supply (and health) must remain open. There are limitations in the access so it's common to wait outside for a while (usually not more than 10-15 min., but it may be more). In the beginning some things disappeared, like TP and canned food, but now stocks are (almost) back to normal.
People can go out to work, buy essential things, walk their dogs or themselves, but not to go to the beach or to wander on the city taking pictures. People over 60 are strongly encouraged to stay at home and let others do their shopping (that's what I'm doing with my mother, she's over 80)
There's been some problems but overall people are engaging in this approach. But it's (slowly) working, with our number being consistently under the best-case projections.
Now we are all waiting to see the curve go down...
