Well duh! Instead of cutting it in 12 slices, just do 8. Problem solved. There is a you tube out there of an english dude trying to see if his girlfriend would like her medium pizza in 12 or 8 pieces. She repeatedly says there’s no way she can eat 12 slices................ Hello? Anybody home?
I worked at a pizza restaurant. I would get asked how large a pizza was then how many slices it was cut into. A standard response to this information was “How large would it be if you cut it in 10 slices instead of 8?” I kid you not.
