I sent DH to get gas at Shell because apparently I have not yet learned my lesson. We get regular gas so I told him to make sure he squeezed in 40 Lts. He came back with 39.032 lts and an response of 'if I knew you wanted 40 Lts I would have done it, it would have fit but I didn't know'. I think I need to pin a note to his coat every time he goes on an errand. The man makes me laugh so there's that!
