Guy: Hi, honey. What time do you get off tonight?
Waitress: Eat your food and take a hike, freak.
Guy: Hey kanojo, can I have your keitai number?
Waitress: Eeeeh?? Giggle giggle, chuckle chuckle, smirk, giggle, chuckle... (walks away)
(The time to ask a waitress for her number in Japan is at the cash register.)
