I dumped a girl once because she had milk and sugar in tea. Not for snobby reasons, it's just that I realised how many minutes of my life I'd spend waiting for a teabag to brew before walking over to the fridge for the milk, returning the milk to the fridge, going over for the sugar, stirring, rinsing the spoon....
All I have to do is boil a kettle, pour onto a bag and walk off. Can't be doing with faff.
(my missus has fancy almond milk... Not only do I have to put up with the faff (she's worth it) it costs a fortune, and you need half a gallon in a mug to whiten the tea. I've tried to educate her, but it's a slow process.)
