Notwithstanding your urge to use the bathroom, you figure it's your only chance to undo these changes and restore your manhood. Working your way from girl scout to ROTC would take years, and you'd rather not wait that long.
You walk your back casually to not arouse suspicion. Fortunately, the staffers were much too busy to pay attention to you. And so, you find your way back to the uniform room.
You walk up to one of the many shelves containing the assorted uniforms, but before you could find a uniform that matched your original measures, the same man calls out for you. "Young lady, I have no time for pranks. Come out this instant!"
Shit. Your lie didn't work for as long you had hoped, but since you've come this far, you inattentively grab a uniform off the shelf and run off somewhere he can't find you –the janitorial supplies room. No doubt you'll have enough time to change into your new uniform here.
