well. statistically they made 70 cents on the dollar of the man's salary, so maybe they have to be more frugal?.A friend of mine used to waitress in NY and she always claims that the worst customers ever are groups of young women and the best customers are groups of men (any age).
The women will ask for the bill and then out comes the calculator on their phones and everything is calculated to the last cent.
The men will get the bill, add the tip and then round it up to the nearest figure easily divided by the number of men in the group.
I’m sure she was exaggerating but I have heard restaurant staff saying that they hate serving a group of young women because they tip so poorly.
When we go out, we ask for separate checks from the beginnings. Each of us pays separately, and tips separately. I always stick to 20-25%. If someone has a salad and one drink, and another big stakes, several drinkis, why would the other person pay for that? Many people are on the budget. Yes, they can afford night out for one person, but not to subsidise their friends.
