Do you have any idea how to prank three people at my table at CiCi's?
Why on Earth do you want to prank these people?
I want them to have a bad experience
It would be wrong to play a prank on them. They are there to eat and have a good time.
I need to cause some mayhem.
Causing mayhem is a pretty bad thing to do, especially to people who just want to enjoy their pizza. If you want to play a prank make it a fun, harmless one, not one that will upset people.
