I made a distinction between being frugal and just being cheap in the belief that you are getting away with something. A perfect example is people who try to extend the number of films or prints put through a fixing bath. This can be either ignoring the manufacturers directions or using a weaker bath than recommended. That they have compromised their pictures does no seem to bother them. Their gratification seems to come from acting contrarian. In a way it goes back to an older post about people who confuse the verbs can and should.
