Not just a thermos............

This my friends, is going to save me, lets say £750 a year.

The only issue with this plan is that I need to get up 5 minutes earlier in the morning so I have time to turn on the espresso machine before I leave, this could be the stumbling block. We shall see.

Well actually not the only issue, the other possibility is that I have drunk said coffee by the time I get to work, and then go next door for a second coffee, this is also a distinct possibility.
