Starbucks Holborn

I was in London yesterday, and I came across THIS...

                                                            

                               ...a queue just to get into Starbucks!

The queue was going all around the inside of the shop too. I later found out it was happy hour, half price on Frapps, So I'm a little less shocked. But still, I dont think its worth queuing that long for a drink just because it's half price? Or is that just my impatience?
