Played Straight: Officer Bob stops at a donut shop.
Exaggerated: Officer Bob's only sustenance is coffee and donuts.
Justified: Dippin' Donutz is one of the few places open late at night and early in the morning, while Officer Bob is working. It's also cheap (maybe even free for law enforcement) and close by the precinct.
Inverted: Officer Bob's Trademark Favorite Food is something healthier than a donut, and in fact, he doesn't really care for donuts.
Subverted: Officer Bob is seen at his desk, eating lunch while grinding through paperwork.
Officer Bob is at the donut shop, but the donuts he buys are for his wife and kids at home.
Double Subverted: But later, he goes to Dippy's and buys a donut and a cup of coffee.
But he can't resist eating one on the way home.
Deconstructed: The new Chief is a seriouslyBy-the-Book Cop, and vows that any officer caught accepting freebies from local businesses will be fired. Bob's wife persuades him it's a good thing because he was putting on a lot of weight eating nothing but coffee and donuts.
Reconstructed: Officer Bob is shown working out to make up for eating donuts, and presents all of his donut receipts during the internal affairs audit.
Parodied: The precinct is located inside the donut shop.
A police car is seen with lights and sirens on, speeding as if to an emergency, and Officer Bob is talking to other cops over the radio...and arrives at Dippy's to buy a box of donuts.
Invoked: While working a late-night patrol or stakeout, Officer Bob gets really hungry and buys himself a donut and a cup of coffee to keep himself going.
Defied: Officer Bob is on a diet, and needs to resist the temptation to eat donuts.
Officer Bob quite likes donuts, usually, but refuses to eat them on duty because he's sick of the stereotype.
Conversed: "I dunno...what if the police officers actually don't like donuts?"
Played For Laughs: Almost always is.
Played For Drama: Someone with a grudge against either police/authority figures in general or Officer Bob puts a bomb inside of a jelly donut and gives it to Officer Bob.
