I always thought it odd that in the Billy Batts bar scene, Billy is drinking with a couple of other guys who clearly have facial hair. One has a mustache, like Billy and the other has a full beard. The "rule" in LCN is no facial hair at all. What is the explanation of this? Those other guys were not "made"? Billy, fresh from the can, would shave off his mustache soon before getting back into the daily life of LCN? Am I too detail obsessed or is this just a Scorsese over sight? Thoughts?
