I used to walk somewhere for lunch almost every day. When I worked in the city, I never had my shit together well enough to take a lunch and save $15/day, so I’d get out of the office to go get a slice of pizza or burrito or something, and get a little fresh air along the way. I suppose part of the reason I didn’t mind it is my job was hella boring most of the time and any excuse to get away was a good one. I paid money to get out of the office, and lunch was incidental.
