Wednesday night, during the restaurant scene, Tom Hiddleston slammed his fork down on the plate, and a piece of melon flew off and hit the floor. He immediately took his fork, reached down to the floor to spear the melon, and ate it off the floor. The crowd went wild, and he and Cox had a hard time concealing their own laughter.
(Though the crowd went wild for almost everything Hiddleston did. That's not a criticism.)
