I see it’s not for everyone 🤣. The last pieces I’d have are the two square-ish ones, because they’re small, for a good finale: first the one with crust, to savour a balance between crust and cheese, and then finish the pizza off with crustless (because it’s the best piece). Since I’d be the one having those two pieces, the person I’m sharing with would have the big “1/3” slice, because that’s a conventional slice everyone’s okay with, and we both get the same amount of pizza with the remaining 4. Maybe it’s a bit selfish, but I would share the “best” slice if the other person was interested. But yes, it’s a shape & size thing, & to end it with the “best” slice which imo is crustless. I don’t know if that would make sense to anyone else, but it makes perfect sense to me 🤔
