I like to play quick games on my iPad/phone during lunch, and I'm concerned if it gives a bad impression. I'm salaried and get an hour for lunch. I eat in the break room usually, so I'm talking about being with other employees. No one's mentioned anything about it or given dirty looks so far.
Our contract explicitly prohibits playing games "during working hours" but this is only during lunch hour; that stipulation was put in because someone was playing games on their work computer instead of doing actual work. Generally the office environment is fairly laid back, and our senior programmer also plays games sometimes at lunch.
Does this still give a bad impression? For what it's worth my boss is always out for lunch, so he never passes by the break room, but many other colleagues do.
