My mate was lucky enough to pick up a Meet & Greet pass to catch up with Metallica before their first concert in Melbourne 
They run a strict strict operation for it though! Limit of 2 things per person to have signed. If anyone is seen trying to pull out a third then BYE BYE. If at any point any band member wants you to leave, then BYE BYE... Basically the way they work is about 20-25 people get a pass. You form a line, and then the band members come out at different intervals. They tell you before it starts that not all members come out depending on how they are feeling, or pre-gig commitments i.e. radio, tv interviews etc. So you might see them all, but possibly only 1 or 2. They even said sometimes NONE come out. Depending on how engaging you are with them will determine how long each member spends with you - normally around 30 secs. And you can ask basically whatever you like. Being that they've done thousands, they are pretty good at it and normally keep the conversation going i.e. favourite song, seen us before, got albums and gerenal chit chat. Luckily on this occasion ALL 4 members attended. Although there was suspense for James as the other 3 had been and gone and everyone thought it was over then he strolled through the doors 
When signing my album Lars was funny... when he asked my mate for his name and he replied that it was Gavin, but this was for Matt, he asked why i wasnt there. Gavin explained that they only give one pass for them but if he wanted to get another i'd be happy to attended at another show. Lars said he really didnt know how these things worked as he doesnt have anything to do with that side of it, but told Gav to tell me that 'He loved me and that he wished i was there'
