Is "confined" a good adjective to describe places like buses, rooms, buildings, taxies and etc. What are other alternatives?
For example if I say
You should wear masks in indoor places.
it only includes inside buildings (based on Cambridge Dictionary).
Does the following sentence convey the intended meaning?
You should wear masks in confined places/spaces.
What are the other alternatives (especially an adjective + noun) to saying that? I appreciate it if you could both suggest formal and less formal alternatives (confined seem formal to me).
At first, "confined space" seemed a very good choice to me but on the wikipedia, it has been written that
A confined space is a space with limited entry and egress and not suitable for human inhabitants.
