My SIL in NZ has been a seaman since he left school and it shows! His garage is immaculate - luckily, my daughter is also very neat and between the two of them the house is always spick and span so there is absolutely nothing for me to do when I stay with them, except sit in the sun on the swinging seat - but I do feed the hens.
My employer in Monaco, although used to having staff to clean the house, was also extremely tidy and he, too, had been in the navy. He told me that if any possession was found out of place, it was put in the 'gash bag' and it cost one shilling to get it back - a good inducement to be tidy, as the wage was just over a pound a week.
