This article was interesting to me because I've been realizing of late, how much money I've been saving by hardly ever going out to lunch since the office move.
At the old office, Ex Hot Ukranian Coworker and I would go out to lunch 3-4 times a week, partially to get the hell away from the office, and partially because the old office was close to tons of great eateries. Being somewhat culturally conservative, I would, because she was female and making less than me, generally pay for her lunch a lot of the time. Probably 2/3 to 1/3 where she paid for mine, so I was spending even more than the article suggests.
Now EHUC is gone and there's not that many other people in the office I would even want to have lunch with, and my office is at the university, where I am stuck with Subway, Panda Express, Dominos, or tons of hippie food, all of which I have to negotiate the 1/3 mile walk through the bike paths of death to get to, or I have to drive several miles, only to come back to campus and even with a faculty parking sticker, have to park a mile away from the office because I lost my parking space. So through negative reinforcement, most days I now bring my lunch and either eat in my office or else take my laptop into the video conferencing room and watch some Netflix on the big screen while I eat my lunch.
I'm noticing my wallet seems to be staying quite a bit fuller. :)
The trick is to having the right stuff handy to prepare for lunch, and having the time to do so. I need to do more of what the article suggests and just have dinner leftovers in the fridge that I can grab quickly and be out the door. I prefer to eat my biggest meal of the day around midday anyway, so it's a habit I need to get into, versus making sandwiches or whatever in the morning while also trying to get in exercise, a shave, shower, and watching the morning business news.
