In Detectorists, Lance's day job is at some sort of vegetable warehouse facility. The work seems to be poorly paid, menial, and Lance is not especially respected by his colleagues.
However, it is revealed in Series 1 Episode #5 that:
Lance in fact won a large sum from the National Lottery around the time that his wife left him.
So if Lance doesn't really need the money, why continue to work at the warehouse facility?
