Please do report on the responses to the silver-grey mohawk. I have been occasionally tempted to dye my hair because I get tired of the seat offers: or, rather, of people who don't seem to want to accept "no thank you" without an added reason: "thanks, but I've been sitting all day" or "thanks, but I'm getting off at the next stop" is less likely to get a repeated offer/instruction to take their seat than "no thanks, I'm fine."

(There's more gray in my hair than when this userpic was taken, but I haven't noticed more wrinkles.)
