“If you are a pack of females, you want separate checks. And I don't mean split evenly by the number of people. I mean split down to the exact number of Diet Cokes with lime each person consumed. And if eight gals order a $14 appetizer to share, that needs to be split into $1.75 each. If you are a pack of females over 55, I'm near tears. You want all of the above, plus you're going to complain about every … single … thing.”
