I have noticed that people, particularly Americans, sometimes say come out instead of come in the sense of arriving at a place. For example, in the 23rd episode of the fifth season of Friends Joey, who is in Las Vegas says to Chandler, who in New-York the following.
Don't come out here!
Interestingly enough, I couldn't find any dictionary that defined come out as arriving somewhere. Is come out used when talking about coming somewhere from a different city? If so, then is it totally synonymous with come in that sense?
