Where do you draw the line in mass production of cups of tea/coffee?

I’m not talking about refusing your tea making skillz when granny and family come round. More to do with flatmates, work colleagues and those sorts.

I’d say I’m willing to make 4 cups (including mine), anymore, and everyone is making their own.

Also, people who request you make them a tea and then don’t drink it/only drink half. SCUM OF THE EARTH.

Also, work colleagues who have particular hot beverage needs.
I offered a woman at work a cuppa (I work with her a lot) and she proceeded to explain that she likes a jug of milk (she is really fat) heated in the microwave for howevermanyminutes, before I needed to add her personal coffee from home, 2 sweeteners and top up with hot water. ABSOLUTELY FUCK OFF. Never made her a drink since.

So yeah, anyone for a brew?
