One of my favourites has the most amazing long luxurious glossy black hair. AFAIK I don't have any hair fetishes *, but it's very common for other viewers to request her to brush her hair for them, or to put it up in a twist or ponytail, and to wash it in the shower....... so maybe it wasn't meant negatively. Or he could be just another rude pr!ck.
(*) although I do just appear to have used plenty of adjectives to describe hers
For me, i read it definitely as being rude. Not even a hello or a single token tip (he was a red name rank 91)... and then to just leave. i think if he wanted a shower show or something else, he would have tried more or something
