When its a bit tight for space around the dancefloor edge,its can be quite a task getting back from B to A.The layout of some of the smaller venues means its almost a military operation getting back to your buddies without spilling a drop.
Most dancers nod,and let you by,but some make it difficult and force you around them and onto the dancefloor!! Try as you might,sometimes it can't be helped.
At the larger venues ,were people dance and drink,there's no excuse.
I'm all for memberships btw.
