The sauce managed to explode somehow and one half of the footlong was covered. This was before Liam even got it out of his bag!
He recommends I eat the other half first, so I try to turn it round without actually touching it and it ends up falling to the ground somehow. Luckily everything was still well wrapped and in the bag and all. Perfectly good sandwich, despite one side being er... covered in sauce. Other side was immaculate!
