Oh leave him/her alone..
Its common for many people discovering Dharma to have a period of being infatuated by The Mystic East..When my friends and I were getting involved with ' Buddhism ' in the 60's at least one of them insisted on eating with chopsticks..
They were somehow more Buddhist..
He would sit there eating sausage and chips with chopsticks...( Vegetarianism having not yet raised its head in Brit Buddhist circles to any degree..in fact for my generation of Brit Buddhists it still hasn't to any great degree. )
Eventually of course one realises that its not about aping other cultures, or lunch.
But its fun to explore.
