the other common complaint is that when you follow the card (at least when it involves free booze) the place is packed like hatians on a raft.
You are often lucky to get a refill if your not posted up in a perfect spot.

I think a lot of it is luck. I went to Lavela's last year one night and it was crazy busy, the only problem was it was like 90% dudes.
Dan Lee had posted that he went to Harpoon Harry's and the place was packed with girls.

Personally, I would go with the advice from a vet on here over following either card anyday....they know where to go and when.
