Slightly cheeky question but I figure worth asking anyway.

Later this week I am flying to BKK on TG with my wife and a colleague. I'm *G. I can only bring one guest into the lounge with me and for fear of upsetting both my wife and colleague I think we will have to take a miss on the lounge for this reason.

However I got thinking that there are two *G lounges (SAS/AC & Singapore) at T3. Is there anything preventing me from going into one with my colleague. Leaving him there. Then going into the other with my wife?

Cheeky I know but is there a rule against it? Is there an integrated computer system that would be triggered by my boarding pass being scanned twice? Would I be blacklisted from Star Alliance frequent flyer-land for years to come?

Thanks for your help!
