Well, Hypo, clearly one's butler knows how family members take their tea, but we aristocrats have frequent callers. Many of these are strangers to him, so he invariably proceeds on the basis that they are almost certainly not MIFs!
(Only joking; you 'ave it 'ow you like, mate!)
I agree with svejk and I eat what I want when I want, if things taste better with sugar on I put it on and I never eat anything but real butter. Life is too short!
