Funny story from blogger David Bogner, an American-Israeli attending Limmud for the first time:

My flight landed well after 11:00 PM on Xmas eve at Heathrow.  By the time I'd gotten my bag and made my way to the nearby hotel, it was well after midnight.  Luckily I'd told them when making my reservation that I would need a late check in.

Or so I thought.

When I arrived at the front desk, the West Indian looking (and sounding) gentleman behind the counter seemed to have some trouble locating my reservation... and they were all booked up.  I watched him poking around in his computer for a minute or two and then spoke up:

Me:  "I hope there's no trouble with my reservation, I can't imagine trying to find a room at this hour.

Desk Clerk [after glancing meaningfully over the top of his glasses at my kippah]:  "Don't worry sir, if there's one thing the hospitality industry has learned in the last 2000 years it is to never turn a Jew away on Xmas eve".
