I'm always rushing around and don't have time to pack a lunch. Even if I did, the fridge space at work is so limited, as there are people on special diets for medical conditions that HAVE to bring their own food.
Plus, I work downtown and we have a tunnel system with TONS of restraurants (many with healthy options like salads, wraps, and sandwiches) so I usually eat Subway most days (their special of the day is only $4.32 and it's good for you). Also, we order in food a lot for meetings and sometimes there is extra food (although unless you know ahead of time you can count on it, they wait too darn long to announce it, I don't like waiting until 1pm to eat lol), or if someone invites you out to lunch that morning, you can accept without worrying about a wasted lunch sitting in the fridge.
Like purse fantatic, I also like to get away from the office. It's nearly impossible to eat up there without someone wanting to bug you about things. I literally was ON my lunch hour and hand a sandwich in my hands and biting into it when some lady came and starting talking and said ok go ahead and pull up such and such on the project drive and I am like HELLO?? Eating??? What the heck. I am taking my full hour thank you.
