I'm thinking of telling the cashier at the drive-thru window I want a hamburger, fries and all the money in the register.
Why do you want to pretend like you're robbing the drive-thru?
I like to do wild stuff like that to challenge the system.
It is bad to try to rob a drive thru. People will call the police and you can get arrested for it.
Fuck, that means I'm going to jail!
Only if you actually go through with it. It's better to not even pretend like you're trying to rob someone, because it makes everyone stressed and uncomfortable at best, or genuinely afraid and possibly hurt at worst.
