Sometimes after eating a burger at work during lunch break I feel tired and my stomach feels awkward.
It can be hard to avoid having a burger, as so many places sell them. But yeah a salad is probably better for you if you have to go back to work, a big burger might make you sleepy and having a snooze at work does tend to be frowned upon by bosses.
I've been having a lot of salads lately as it's just too damn hot to be bothered with cooking. Which has surprised my wife as I'm not really a fan of salads.
That'd depend on what else they toss in there.
True enough, I've never been curious enough to look at the ingredients so it shall remain a mystery.
