DEAR ABBY: My wife and I were out to dinner with two other couples who are also good friends. We all enjoyed a couple of bottles of wine during our meal.
When the check came, we split it three ways. However, one of the other couples insisted that we should tip only on the food portion of the bill. I said we should tip on the entire bill, including the cost of the wine. Who was correct? -- PROPERLY SERVED IN NEW HAMPSHIRE
DEAR PROPERLY SERVED: You were. The tip should have been computed on the entire tab -- and that includes the wine that you "all" enjoyed with your meals.
