The topic came up at our weekly monday morning status meeting.  AJS noted my tea was 'frothier' then his.  I told him it was because I put the milk in first, then added the hot water.  As an uncultured American from the midwest, I did not realize there was such controversy around this topic.  The ex-UK residents in the room immediately dismissed my claims.  I pointed out that Douglas Adams suggested this was the correct course of action, but they were unconvinced.  Today I found an article which seems to back up my story.  Miss Manners disagrees, apparently, but I never liked her anyway. 

Of course I gather the fact that I am drinking Earl Grey made from packets out of a little box in expanded rigid polystyrene plastic instead of some sort of expensive china is probably abhorrent to the sorts of people who worry about these things, regardless of the order in which I introduce the milk.
