There was a place to plug his laptop- in, but he didn’t have an adaptor with him, so he had to save the laptop on the battery. Anyway he switched the computer on and found there was a free wi-fi network so he got a user name and a password and logged on to the internet. He surfed the net for a while. And he found some interesting files connected to his work that he wanted to download onto his hard drive. So he started to run them. While that was going on, he went off to get something to drink. When he came back he found that his computer had crashed. The battery ha run out, of course. And not only that- his plane was delayed for three hours and he couldn’t use his laptop any more.
