My mug at work is really grubby. As soon as I've had one cup of tea in the morning it has dribbles all down the side, and I've noticed that no matter how carefully I sip, there is always a drip of tea on the lip. The inside is covered in tide marks.
Nobody else at work has this problem, their mugs are all shiny and lovely at the end of the day.
I'm worried that I sit and drool involuntarily down the side of my mug and everyone is too polite to mention it.
Does anyone else have this problem, or is it just me that mings?
