Well, I’ll tell you, seeing as you didn’t ask.
Once a week, I work in a different office to my normal one. I have my own supply of teabags and milk - but no spoon. HOWEVER, the teabags are PG Tips pyramid bags, which have a nice handy corner that floats just above the surface. So I can give the bag a bit of a swoosh around the mug and then remove it without scalding myself.
