You're driving along at night. There appears to be some kind of commotion up ahead. You're the only car on the street, but you see a car pull out of a driveway at breakneck speed and head off. A cop comes running up to you. "This is a police emergency. I'm going to need to borrow your car". What do you do?
You're walking your dog (pretend you have one in this scenario). Near where you're walking, there's a dog show. On the corner where you pass, you see 3 cops and one plain-suited undercover cop. You hear them say "he's definitely in there. We need to blend in, but where can we find a dog on such quick notice?". Then they notice you. "We're going to need to borrow your dog. Official police business". What do you do?
You're at the mall. It's a crowded day. Near the nicest restaurant in the mall, you see a few cops, and one undercover cop (of your gender). You overhear them talking about the undercover cop will have to go in and masquerade as a server, but word quickly gets passed that the servers in there wear black pants. The undercover cop is wearing grey. "There isn't time to hit a store. We need to get in there now!" Then the cops notice you. Boy, this was a bad day to wear black pants. The cop looks roughly your size. "Official police business. We'll need to use your pants. Here's $50 to buy another. ASAP!" What do you do?
