Strangers

I go to work. And in our office we have this very lovely machine that makes coffe and hot chocolate and other related drinks.

The problem is I don't want to use the shared office mugs with the rest of my very interesting mix of colleages.

However I can't label my own mug either cos the name will get washed off by the dishwasher we all use at the end of the day.


So how do i bring my own mug to use whilst avoiding others to accidentally use my mug?

Any help is appreciated.
