He offered it to how many and only three show up? H*ll more goys would have showed up with the offer he made.
Here's a Jewish stereotype for you:
A single Jew was found once on a remote island. When asked how he got there, he responded that he was the only survivor of a shipwreck many years ago. And since the island was so remote, there were no communication options, so he couldn't get off the island, but made the best out of it, and even created his own Jewish life there. He then showed off the two synagogues that he built. When asked why does a single Jew need two synagogues, the reply was one to worship, and another where I won't step my foot into. (Just read the DDMS post and comments about the WAJ kosher status for relevance).
