There is more to that story
The man who did not like Chulent was a Charedi bocher from an eastern European country whose backround could not be checked, He went to an Averch and did not eat the chulent, The avereich was afraid that the man was a min and thought the man ruined his wine. He then asked Rav Elyshiv what to do.
They could not figure out his exact backround since he was from some eastern european country (I am assuming it was from one of the former soviet union countries)
