In the real world that would be fine, but we are a GA tower where the majority of our traffic is military pilot training from another airport. They train mostly over here for practice instrument approaches. They can accept a circle but then the instructor would have to take over, student would have to be vectored around and try the same thing again. Now i would normally have no problem with that but it's kind of a political situation i guess. We don't wanna piss off the majority of our traffic. We try and work with them the max extent.
