The greatest thing since bread sliced to order

Stopped at a grocery store in Utah and asked the supermarket bakery to slice a loaf of bread for me.  I was a bit taken aback when asked, "What size?"

Never been offered that option before.  Didn't even know that bread-slicing machines are adjustable.  But apparently everything has a standard.   Ideal size for a PB&J is the #12.
