Another way in which behaviours can be changed is through the use of affordances – which make it easier for Singaporeans to commit to change. In this case, reusable containers could be made more readily available at hawker stalls. This is similar to how supermarkets such as NTUC have reusable bags on sale at checkout counters for customers to purchase.

However, it must be noted that while this suggestion should work in theory, it is less feasible in real life.

Firstly, most hawkers will not be willing to bear the additional costs of purchasing reusable containers for customers, especially since they cannot guarantee whether enough customers will purchase them.

Secondly, while the government can provide these containers to hawkers, it is not a cost-efficient and sustainable method. For this to work, research and trials will need to be conducted in order to gauge whether there is a demand for reusable containers, as well as determine how receptive Singaporeans are to this idea. Even if people agree to purchase a reusable container, there is no guarantee that they will actually remember to use it.

Lastly, hawkers will have to make a conscious effort to prompt customers and ask whether or not they would like to pay additional costs for a reusable container. Nevertheless, prompts from hawkers can be used to remind customers to bring their own containers, or at least, prod them in the direction of doing so!
