well the ingredients of a white russian are vodka, coffee liquor, heavy cream and ice
so a virgin white russian would be debatable how to make (what do you do with the coffee liquor?). but PERSONALLY what i would do if i was the bartender is probably just coffee, heavy cream, and ice although some bars have non alcoholic spirits so maybe some replacement fake vodka too
so either a HECK OF AN ORDER or maybe just a super confusing way to order a strange iced coffee
