I recently had a tank make an AK run take 2x longer because he wanted to save 500 Gil on repairs. Now, you might think "another speed run fight" but no, instead of using his AF gear, he switched to white gear, took all his accessories off, and tried to tank like that. Needless to say it did not end well and we wiped, then the healer leaves, we find another, etc all in all what could have been a 20 minute run turned into an 80 minute one; over 500 Gil.

I would say this inadvertently affects everyone, because people are extremely stupid and being poor only amplifies stupidity.
