5 5-star review from an employees friend

Really not sure what to say. An employee brought his friends in. He used his $500 employee comp tab they paid $500 on top. Friends all left wonderful 5star reviews naming the employee (a cook). I should be super happy right?

For context: I’m friends 😭 he invited us all without telling we won’t pay and it was more than he expected and won’t take money back. We haven’t left the reviews yet because we don’t want to get him in trouble. We thought restaurant would love that! No?
