Bar Grub

If you are in a bar and a man or woman (depending on your preference) is next to you offer them a drink. After you have done that if she says yes then ask her if she/he likes "dat bar grub" if he/she says yes then get them a packet of crisps from the bar

Peter: Did you go out last night, did you ask anyone out?
David: Nah, but she likes that bar grub though
