"... what kind of coffee them Lundun QI elves drink all day long ..."

That brought to mind something I realised recently, regarding discussions about whether to put the milk in first or last when making a cup of tea. This began when people made tea with loose tea leaves in a teapot, then when it had brewed they poured the tea into delicate porcelain teacups. Putting milk in the cup first meant it was less likely to crack when the hot tea was poured in.
This morning someone described making a cup of tea by putting a teabag, milk and a sweetener into a mug and then adding boiling water (ughh!).
Putting a teabag in a mug is now considered normal, it seems. I do use a mug, but I make the tea first, using loose tea leaves in a teapot.
