I was in St.Pete Russia in Metro. There were two guys who were selling some stuff in the train and on each station they were going to another car. One of these guys was selling maps and pensils. Good and usefull maps and not bad pensils. So there were potential buyers in the train, but when he was describing his article of trade noone will be able to hear him and everything what he was talking about was boring and not interesting at all. There were no smile on his face. So, he hasn't sold anything.
Second guy was selling real stuff - something like balloons with a sound. He was talking loud enough so everyone will be able to hear him. He has shown how this balloon works - he has inflated one of them and let them off - balloon was flighing with a funny sound throw whole car. Everyone seen that, and he has sold 5 or 10 such balloons in 2 minutes.
So - good marketing and presentation are working really well
