I typically tip 20 percent.
Why are women such stingy tippers?
Women are bad tippers because generally wait staff is young and attractive. Women don’t much care for other women, especially younger and cuter ones
Women are generally more judgmental about service. When I'm out with male friends, they get irritated about poor service, but don't correlate that to the amount of the tip. My women friends do. I do. I am very generous to friendly smiling service, but don't feel like being taken for granted and express it in the tip.
