Wondering if anyone has had any experience with this "hypothetical"...

Let's say you needed to leave the country and return to get a new entry stamp in your pasport after you are about to pass the limit of the previous one. Could you buy a refundable ticket, check in and go through passport control to get the exit stamp, then tell someone that you wanted to leave the airport, and go through arrivals?

There is no real restriction on getting a new stamp in this imaginary country. Many people simply take a bus to the border and then turn right around and come back.

The one thing I'm mainly concerned about is that unlike CDG, this airport doesn't mix arriving and departing pax, so I'm not sure whether I can get to the arrivals area without some sort of official intervention...

Ok.. try to imagine an airport like... hmmm.. I dunno... IST maybe

Thanks in advance for any input.
