If there's anything that gets on my nerve more, it has got to be a sales person who tries to make you buy things you don't need. That was exactly what happened when I went to the pet shop to get some toys for my new dog. The sales girl tailed me around the shop and tried to sell me every product that I so much as glanced at. She was also a non-stop chatterbox who was more concerned about my money (becoming her money) than me or the pet she sold me. The poor girl still couldn't figure out why customers are running away without buying. Thus the desperate, sure-to-fail, plea to buy, buy, buy.
