Here's an experience (quite some years ago) with a different take -
Me, back seat of a Cessna 172, experienced PPL plus instructor as a check flight for the former. In the circuit, instructed by ATC to advise turning base, call duly made, with response "caution wake vortex" (737 clearly visible just passing over the threshold). Also we hear another light aircraft joining behind us. Instructor immediately tells pilot to carry out a RH orbit. During the orbit (or maybe on completion, I can't remember) ATC calls "Instructor, report to ATC immediately on landing". I'm no expert (obviously) but even I twitched a bit!
