Working in East London I become acquainted with a couple of white lads with Jafakan accents. Good lads I liked them. They asked me to take them on. I said I wouldn't because of their Jafakan accents. They both agreed that is what was stopping them from getting on on life.
I took on a young very intelligent Black German lad who knew how to present and conduct himself. Unfortunately it was not the trade for him.
But it is so important when entering people's homes and the way you speak is very important.
