TGIF! Well, that happens tomorrow, but once the weekend euphoria is over, it is back to the daily grind of working at the office when Monday beckons – unless, of course, it is a public holiday. For those of us who need to get our daily dose of caffeine (or a favorite hot beverage), then we surely have a mug marked as our own at the office. Why not chase away those Monday blues with the £14.99 Monday Mug? Yes sir, this mug might look really sulky at first glance, but the moment you pour hot water in, the front will be replaced by a bright-eyed smiley one. Definitely perfect to chase away those blues feeling, although it does seem to be rather overpriced.
