"There are extra units in the box..."
(In fact there were spare hand held microphones in one of the boxes in the sound booth. Calling them units was a direct quote of the email from the sound designer.)
"So, we need more screws?"
(A pair of eyeglasses fell apart onstage, and the repair kit has no screws big enough to fix them.)
I can't believe we have to do this twice again tomorrow. Whee!
