LOL
Just look him angrily in the face and bite the banana in half. Thats how you beat this, NOT calling the cops to try to prove someone did it intentionally lol. Tell me how will they find out?
If you can prove it was done intentionally sure but its impossible to prove he has a bad legal representation i guess? Also this kind of sets precident about fruits and races? Best watch out who you offer fruit too!
It would have been easy to find out.
The police would have gone back to weatherspoons and would have looked at the ordering system to see who had ordered the banana. I can't remember if you need an account to use the app, but either way he would have had to put his card details in or paypal to complete the purchase, all which would have linked to the person placing the order.
The guy was clearly an idiot, and knew exactly what he was doing. If he'd ordered an apple with the banana then it would have looked more like an accident.
