Well, THEY know they're attached, so if they gave your their phone numbers, then 1) they're OK with you calling them and 2) they understand that you're not asking them on a "date" (since you know yhey're attached). I mean, YOU know it's not a date, right? Just like asking a male co-worker to join you at the bar after work, except they're women rather then men.
And if they ask to bring their boyfriends, then that's fine. After all, it's not a date. And if you're extremely lucky, they may bring a female friend along. Don't count on it but be prepared in case.

I've somehow ended up with the numbers of some (ie. 3/4) of the people who I work with.
Although, I am curious about this "somehow"... They know you have their numbers, right? You didn't "Google" them and stalk them did you? lol...
Actually, the mechanics of this "somehow" might benefit some of us on the site, myself included...did you find the balls to ask directly?
