I worked in a company that was engaged in the assembly and service of express payment terminals. And then one day one terminal was hanging on the service, and the tachskrin did not want to work with him. They gathered, began to check. And came to mind a brilliant idea, connected the monitor to the computer, on which was installed IL-2 strike aircraft :-) Who played, he will understand :-) That is, when you fly, you mean, over Belin and straight hands steered you turn, the fingers of each button you use - 100 percent realism :-))) The work stood up for a week, all the employees of the company built in a row on the airplane to fly" :-) In the first rows stood the head of the office, with the words "Yes, they went into the ass these customers, I still did not bomb the station" :-)
