I once did some work for a business that operated in this field. I'll never forget the owner. He had done very well over the years and drove a Ferrari - an extremely rare sight in the industrial area. He spent all day selling very high end second hand and new office furniture to discerning clients - large contracts for whole buildings sometimes. But in his own office he sat on the very cheapest office chair that money can buy. One that he wouldn't have been able to source from any of his suppliers. Never could figure out if it was a contrived statement, or not.
