I used to buy my breakfast from the office cafeteria and surrounding shops in the past. However, recently I've started bringing my own breakfast from home. I usually put some bread in the oven to toast while I'm getting ready and when I'm done, it's perfectly toasted. So all I need to do is to pop it into a tupperware and I'm ready to breakfast in the office. Although buying breakfast doesn't cost me too much, I guess every little bit of savings do count.
