My husband took his staff out to dinner and one person in the group ordered a $70++ after-dinner drink[whisky]. I honestly don't believe the gentleman knew how expensive it was nonetheless, it appeared on the bill. My husband was mortified but didn't make a scene in the restaurant. Is it appropriate for the waiter to disclose the cost of the libation if it is way out of context with the rest of the meal? Should this happen again, how do you recommend he handle the situation?
