For this riddle, I have two homophones, however the first one is a single word and the second one is composed of two or more words.
Example:
h1 - licensing
h2 - lies and sing OR lie sensing
Try to guess h1 and h2 in the following situation:
Police officer Steve and his partner Fred are taking a break from patrolling by stopping at a donut shop. Steve is waiting in the car while Fred is walking back to the car from the shop without any donuts.
Fred: Steve, we have a(n) {h1}.
Steve: What is it?
Fred: {h2}!
HINT 1:
The answer has more to do with their occupation than the donuts.
