It was brought to me that Frau Jolene is giving free food to masses.
With a little logic, we all know nobody except Gilbo gives anything away for free in Rapture. When I open the sandwiches, I had lots to see.
My experiments and genetic testing show those are Wursts of Andrew Ryan. It is amazing discovery. Whenever they are cut, they grow again. However, experiments show they have been to lot of places before they are cut.
Children, you are not allowed to eat those sandwiches. Especially not you, Jack.
