Is this really part of orthodox Christianity? How on earth do you tell a co-worker, look, you're a Hindu, a rotten sinner, we cannot eat together in the cafeteria? Most Christians (like Kenny Jones) would end up eating alone everyday. And be fired for bad attitude.


No, it is not. Jesus ate with the sinners all the time. That's one of the things the Pharisees criticized him about. Eating with the heathen is an opportunity to show Christ to them (even if the subject is not brought up) by virtue of them getting an insight into our life. This is "witnessing" as opposed to "preaching". A different set of rules applies to witnessing. We never see Jesus in one-on-one situations telling folks they are hypocrites, vipers and fools. That was reserved for open-air preaching, as the apostles also did.

The Scripture warns us not to eat with professing Christians who are in gross unrepentant sin:
1 Corinthians 5:11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.

Anyone who shuns unbelievers simply because they are unbelievers is not appying a Biblical standard to their associations.
