I remember a time I was working for a sports car manufacturer building a DR system for them. They put me in a cellar as it was next to the machine room where I had to be most of the time (plus it was about 150m from the test track so all day long I could hear vroom vroom as well.) Anyway, after a few weeks down there with a nutty German who used to pop in occasionally as it was his office/workshop as well, I was joined by 3 chaps from India who sat kind of opposite from me but never talked to me. Apparently they were working on some software called Remedy application and all 3 of them used to sit huddled up next to each other around a laptop talking to each other in English but never said a word to me. A lot of the time was spent on the phone to some people elsewhere and the conversation used to be in the region of 'what do I type in here?' and 'how do I do that?' You get the drift, it probably would have been easier for them to just say 'look we haven't got a clue, get us out of here.' One day, when leaving the cellar, I wished them a good evening and hoped that they were having a pleasant time and if they had any problems then to just ask me, all in the Queens English of course. The next day the volume dropped considerably, the amount of calls went down and the faces looked more and more panicked. A couple of weeks later the project was cancelled. Apparently they had already been there 5 months trying to get Remedy working and the car maker was not too impressed with outsourcing work (except to me!)
