Aha, now I understand. In these "communities" for Western expats, yes there were plenty of Christmas festivities. I was there in the 1980s. We were told to avoid anything symbolic of Christmas when we went to KSA. Riyadh was noticeably stricter than the coast (Dhahran or Jeddah). The General Manager of the local company in Riyadh sent me a card with a picture of a peacock, inscribed: "Whatever is wonderful, whatever is beautiful, may it be yours, at this holiday time." He wrote underneath: "Hint, hint!".
So yes I did think a Christmas pudding was risky, given the arbitrary behaviour of customs officials at Riyadh airport. I removed the label and proposed to tell the inspectors it was just a traditional British delicacy. In the event, nobody looked at it.
Mind you, at Jeddah, I was told the Filipino community not only actually managed to make pornographic films there, but
exported them! I take my hat off to them for that.
