'Clean and neat' is to some extent subjective. Its going to take some work to overcome personal biases but still have reasonable standards.
I agree.
I had help once who had dread locks. Wasn't really my cup of tea, but everything about him was clean and well-groomed.
Just this past week I tried a guy.
He showed up with his pants sagging below his ass, and his pants were torn in a couple of places. I was immediately like - umm, no. There isn't any way you're coming into my job looking like that.
For me, here's the bottom line.
If I have to drop you at the front door of my job site, is the customer going to be intimidated or feel threatened by the way you look?
It's got nothing to do with race.
That guy with dreads I mentioned, he was black.
Nice guy. Clean. Well-spoken, too. From Jamaica.
The guy with his pants sagging is white. Looked like he crawled out from under a trash can. Dirty and unkempt. Nice guy, but needs to clean up
