Pretty much, but it goes well beyond knives though, people like that will try and cheat you out of a penny.
They will drive 50 Miles to save 5 Cents, even though they are spending a lot more than that just to get there and back. Try and explain that one to them, just try....
I have had people argue with me over a penny, really putting up a fit about it.
People can do what they want, but the frugal ones need to stay far away from me.
One the knife topic though, I can't count how many time I have heard this (Enter Cheap gas station Knife here) is just as good or better than (Enter Quality Knife here) and they will argue it to the death.
I have been down that road getting someone something nice only to have them sell it then lie to me about it later, and they weren't poor or bad off either...
I have heard a person that I know talk for 15 mins how they saved $10 by really going out of their way and making a huge deal out of it, making more than one trip etc and they are worth Millions..... Do you know how pathetic that sounded to me.
