BTW, I’ve read it is better to approach a two-people group (instead of one to one) for several reasons, one of them being you can leave without making it awkward.
Other reasons (not related to extraction):
– You get to know two people instead of one
– People are less worried about being stuck with you the whole event so they are more open an chill
– Double the chances of it not being a disaster and a bore
– They could be both “massage therapists” or “electricity people”
