lol blind date, dont do that.
if he makes friends with her (assuming theyr both no socially retarded as its not hard to be friends with co workers) then all he needs to do is arrange to hang with her and her friends for drinks (prefferably at his place for a home ground advantage.
When you hang out with friends of friends you already have social proof and it is rediculously easy to talk to the girls.
Also since they arent going to go anywhere you can ignore them a fair bit at first, be entertaining, joke around with your friend (or friends), tell stories to the group, slowly giving her more of your attention as she demonstrates value to you
Also teasing her is good "how much are you girls paid to hang out with this one (point at her)"
Basically girls are much more likely to get with a friend of a friend over some stranger they met on the street/in a bar so be that friend of a friend. just set up the situation. (this is also why building a large social circle through doing many interesting things in life can get you laid more easily than sarging in my opionion. it also makes you a more interesting person- but thats me going off topic
)
