Change is inevitable except from vending machines?

The phrase "Change is inevitable except from vending machines" humorously highlights the idea that while change is a constant in life, there are certain situations, like using a vending machine, where we expect things to remain the same. It underscores the frustration we often feel when we can't get what we want despite having paid for it. This juxtaposition serves as a reminder of the unpredictability of life, even in mundane situations. Ultimately, it suggests that while we can anticipate change, some experiences can still leave us wanting.
