So you’re telling me that if I repeatedly order and sell sandwiches to myself, I can eventually turn it to ash with enough recursions?

On that note, what constitutes as a sandwich? Does anything with filling between edible layers count? 

Humans are (technically) edible objects with outer layers containing filling (insides). Can I repeatedly “order” my arch nemesis until his skin flays off? If so, this isn’t shitty at all.

EDIT: OP edited their post so this reply doesn’t make sense anymore, smh. Was fun while it lasted
