When we first moved into this area we went to do some shopping at the local Waitrose and Hubbie commented that is was 'very white.' I remarked that the green and white decor signified freshness and cleanliness and he clarified by saying, "No, I meant the people. They're all white." I looked around. "Not everyone, the counter staff aren't."
It wasn't a judgement, just an observation. One that I hadn't made. In the same way I didn't notice until someone pointed it out to me that my chosen profession was staffed almost exclusively by women who were white, blonde, 20-something and (in the old days) trustafarians. It wasn't an issue as it didn't stop me doing my job so I thought nothing of it.
