I believe the Italian man. I believe that he was just joking. The Afri-lady was with a Spaniard and a Japanese national when the pellets smacked the ceiling. I understand that the Japanese was a member of the club. I have doubts that the Italian uomo would have thought the Japanese white. Plus, if there was real racism going on, why would they not simply make it a private, members-only gig? Why would they allow non-whites to walk in and eat, and only withhold membership with its (usually) dubious benefits?
That said, I believe it was a very lame defence for the Italian man to say the fact that he was married to a black woman was proof that he was not racist. Very lame!
So, I believe that it was a mere jackass joke, and not true jaundice.
But the joke exposed him. He was operating a legit, front-room, raw seafood shop and an unlawful, backroom, seafood eatery. He evaded certain taxes by giving worthless scribbles on paper as receipts. He was cheating the nation.
So, a cruel, ill-thought, stupid, unnecessary joke exposed the poor man to odium, opprobrium and ‘government matter’. Hopefully, he thinks before he speaks next time, but I don't think he is racist. Enough of this row now.
