You work as a police officer at the border post at Acaristan. Cars come and go, and you've done excellent work in checking every single one of them. You need to check these things from the drivers:

-Matching IDs -Matching names -ID expiration date -Matching luggage amount (For example, if the driver has signed beer barrels 5x and cement 2x, you should make sure he has brought exactly the same amount with him) -Also search the car for hidden alcohol bottles or drugs (Use UV-lamp to find a snake logo)

Turn back everyone who violates the regulations above and arrest everyone trying to smuggle alcohol or drugs to Arcania.
