Why do I or should you care about frugality? Does it really matter if we don’t count the freebies of life in our frugal measurements?
Actually it does if you consider your impact on the climate and the world at large. The impact on the environment is your concern as it does affect quality of life. If you dump pollutants into the air with reckless abandon you by default give permission to others to do the same. When the herd of lemmings run off the cliff in synchronized fashion it makes a splatter spot at the foot of the cliff noticeable to all.
Keeping spending low by pushing the cost on somebody else is a bit rude, but acceptable in our modern world. The spending shift is sometimes by design of those doing the paying; those without any real frugality concerns. These gifts are nothing more than inducements to get you—or others in your sphere of influence—to take up the additional consumption.
