That is utterly disgusting.
One should always put the milk in first!
What's disgusting is, you would put milk in tea....you probably use sugar too....
Don't be a cretin. Tea is taken with a little milk. Milk first and no sugar. The tea itself should be from India or Ceylon tea bushes, anything else is not tea, it is an infusion.
Traditionally, builders (or other tradesmen) will take very strong tea with lots of sugar, but they are uncouth and need their strength.
