I started a new job over the summer. In previous jobs we've had a staff room with tables and sofas so room for staff to sit and eat their lunch/have their break if they want to. My current job has a small kitchen with only about four seats for an office floor of at least 25-30 people. When the weather was better I sat on a bench in a nearby grassy area to eat my lunch.
If you don't want to sit at your desk at lunchtime, where do you go to eat your lunch if it's raining/snowing/freezing outside?
