This is how it's done, fellas
Inside a restaurant. There are two bathrooms for one person - one for men and one for women. They are both occupied. An attractive woman gets behind me in line. She smiles at me unprompted.
Her: Normally there's only a line for women.
(Ok Lee, time to turn on the charm.)
Me: I'm a woman.
Her: (laughter)
(Not your best effort, champ.)
