I volunteered to assess some third year presentations. The students’ assignment was to sell me a computer system. These lads – all mature students well into their forties – exhibited some sense of humour, turning up to perform their pitch in cowboy costumes. They started well, but lost the plot when I asked what kind of discount I might expect on any purchase. It was obvious that they had not considered that haggling over price was a crucial part of the repertoire of any computer sales professional.
