9. Fast Food
Lots of people eat fast food for lunch, but we don’t recommend doing it at the office if you are trying to score a promotion. Honestly, it just looks childish.
The smell of fast food also lingers for a very long time, and while it is not the worst smell in the world, it does get tiring.
A lunchtime meal loaded with fat, sodium, and sugar may also make you feel bloated and gassy the rest of the day. Let’s face it – having to pass gas at the office is not a pleasant proposition.
