Does beauty sell? Conventional wisdom says yes

I recently overheard a conversation about a bank famous for employing beauties in its front line. One man even suggested they should return the beauties for the business to prosper. The man suggested he could visit the bank without any transactions, just to hang around, full of hope.

That left my head spinning. Does beauty sell? Would your sales go up if you employed women perceived as beautiful? Conventional wisdom would suggest no, the customers know what they want and beauty would not distract them.
