Cream should never go in tea. Milk goes in tea

This is a long standing joke and point of annoyance within the UK hotel industry, because so many Americans ask for cream in their tea, thinking they're being locally knowledgable 

Using cream--usually half and half in actuality-- in tea or coffee is common in other areas of the US, but not here--milk.  When you hear someone asking for "cream" it is a tourista!  Also, the tourists drink hot coffee with the meal --coffee or a demitasse is post dinner.  And the final carp on coffe in the US generally is that it is thin, watery coffee in other places--coffee should be, as the old French expression says, "Black as the Devil, Hot as Hell, and Sweet as Love!"  For cafe au lait--breakfast coffee, a pitcher of hot steamed milk and a pitcher of hot black chicory coffee are poured simultaneously into the cup.  Cafe Brulot is a dessert drink made with hot coffee spices, liquors and then flamed and put into brulot cups. 
Tea--a cold iced  drink served year round with a wedge of lemon.  No milk or cream  please.   Or hot, it sits at ladies' teas and luncheons while the ladies slam the wine, the tea is there for window dressing.

Ahem,ahem.

Ask the tea drinker if she prefers milk, sugar or lemon and add it to the drink prior to pouring the tea. Pouring the tea over the additions allows it to fully mix. You should serve lemon slices, rather than wedges, as they can "sit" in the tea cup. Always put the milk in first, followed by the sugar and ending with a lemon slice.

Hey those are the "Ladies" rules--not the gents!   And what do you do with the pinkie finger?
