i agree with your definition of well groomed, but the types of people usually in control of these work grooming policies dont all share that same definition, hence ‘grey area’.

your...OUR clean and neat is NOT their clean and neat

if one of us needed a cut bad but didnt have time, so we got a shape up with a line. most yt folks cant tell the difference.
then ive seen some yt folks that think a line is a fancy haircut when they see it. they dont understand why we get lines.

meaning, a lineup is what we get to make our hair neat. meanwhile they dont even see that shit, if they do they think you on some fancy shit

different definitions.
