For someone 21 years old and starting the first leg of work experience, yes, there's a time and place for showing it off. This isn't it. You've seen my tattoos, Amy. I'm where I'm at now by not flaunting them off, and people like you and I have earned the priviledge (to an extent).
But to the guy in here looking for a CIO or CFO job paying $150k/yr after 13 years in the business, I'm sure he won't get another position with a hunk of metal through his lip or a stain of black on his arm.
