mate it should really be up to them to prove your guilt and not for you to prove your innocence. ever heard the saying innocent till proven guilty. fuck em if they're gonna acuse you of that then tell em fuck off and get another job. if they have footage of you paying for your drink in the till they should have footage of you taking the money out. and if you didn't nick it then they obviously havent got the footage. tell em balls and be insulted by it. don't be scared of gettin in trouble ocs you havent done anything wrong.
