Every coin has two sides.Each action has good and bad sides.So,I'll start with the positive side.In today's world people are very busy, they rarely have time to cook, and long-term food intake.And this way of eating allows you to save time.On the other hand a quick bite very harmful to the body and can cause various diseases.As well by eating in public transport, you can drop the food or stain someone.However, at the moment to a quick bite on the run resorted more and more people.As for me, I believe that much more useful and more enjoyable is having a snack at home or at the cafe.
