I offer pencil portrait drawings based on photographs in England.
Client: If you drew a portrait of me and my husband, how much would that be?
Me: Depending on what exactly you want, it starts at [price].
Client: Okay. But since that would be black labour, I won’t pay you. I could get into legal trouble for that.
[Editor’s note: in England “black labour” is illegal work that is not taxed.]
