Marmite tactics

J has been having a problem at school with his classmates stealing his snack meaning he comes home rather hungry. So we hatched a plan: Marmite sandwiches!

The plan is that even though they may get stolen the first time it won't happen again as hopefully they won't like Marmite and will learn their lesson. I've also wrapped his snack box in a very russtley bag so when a thief reaches into J's bag to steal the snack he'll catch them red-handed. If this doesn't work he's got a stash of biscuits in his shirt pocket which no one can get their hands on I hope!
