I used to know a bloke, nice guy, used to meet him for breakfast in Ocean Village when I was on Gibraltar, he moored his yacht there, he had a very successful import/export company, multi-millionaire.I once asked him had he ever moved anything other than what he was doing, he held up a small finger-sized lump of Moroccan and said "No, because you can make as much money as your ever going to be able to spend in a lifetime moving this stuff, with quarter of the bird and hassle associated with powder".
