How to test
Make a new Food event and set the time to expire in like a minute. Try to order food when the food event has ended if you are back to the index page of pizza, then this is correct. You should not be able to order food when the event has expired. Make a new food event and do not register for the event that requires registration, then try to order food if you are redirected to the index page of pizza, this is correct. You should again not be able to order food.
