this happened to me in the simulators.
I was controlling and my fellow colleagues-students were on the other side, piloting.
By th way, I am spanish ,and thus have a distinctive accent , and my colleagues are all english native speakers.
student ( that is me) :
F50, traffic information for you, BE10 on left downwind rwy 24 nr1. you are nr.2 behind that traffic.

everyone had taken their headsets off and couldn't continue the exercise....
