6. Meals sold at on-the-go eateries have steadily become more expensive.
Fast and convenient meals have steadily become more and more popular. Across most major cities, there is an abundance of on-the-go eateries which offer prepared meals to be purchased and consumed straight away. The fast food revolution was typically associated with unhealthy food - food which might not be beneficial to the customer but rather profitable to the provider. The future consumer expects their convenient meals to be healthy too – or at minimum, freshly prepared. In many cosmopolitan settlements, on-the-go eateries have been born, or converted into, health-conscious food outlets. This suggests a trend that most customers desire food that is fast, convenient but also good for them.
