This thread has reminded me of the way tea was made on the building site when I was a student.
Take one fairly clean galvanised iron bucket, fill with water and place on fire
of wood offcuts in oil drum. Add one whole packet of loose tea and can of condensed milk, stir once and bring to boil. Bring own enamel mug and dip into bucket. Foreman gets first dip, followed by senior tradesmen. Labourers go last and get tealeaves.
Canny student volunteers to make tea next day and gets dip in even before notifying foreman tea is ready.
