Here in my country, we usually use the expression "where are you coming from?" as a greeting. (It literally means where you were before you got here).
This is good manners to ask like this in our country, but I heard this is a really inappropriate expression as a greeting.
When we meet each other, and we are a little bit curious about where someone is coming from, what is better to use in the elevator or in the street?
How about the expression "Are you coming from work?"
