People who save every plastic bag as adults usually do so because of the frugal beliefs they grew up around. These beliefs caused them to develop a frugal and scarcity mindset that dictates not only the way they spend money, but also the way they save it, how resourceful they are, and how they budget for their future needs.

They will want to find ways to repurpose items they already have and always try to avoid spending money on items that they already have or that they really do not need. Their upbringing has allowed them to develop a self-sufficiency that benefits their long-term financial needs and goals.

Even if it has a tear in it or is messed up in some way, they will choose to find a way to mend it before they throw it away or choose to replace it with another plastic bag.
