Double up on lunch for a colleague

As anyone who's suddenly moved in with a partner knows, cooking for two is more efficient and price-effective than cooking for one. With that in mind, the next time you're preparing your lunch, why not make another portion for a coworker/fellow student/customer/whatever? If you want to avoid the appearance of workplace favoritism, you could always leave the extra lunch in the kitchen with a note saying 'Eat me [insert non-threatening emoticon here]'.


Effort involved: since you already have the ingredients lying out, it's getting double the impact for less than double the effort. Score.
