That isn't - by my definition - being thrifty. That is living within ones means, perfectly acceptable.
Being thrifty/tight/mean to me is saving money for the sake of it even though you don't have to. My brother-in-law, as an example. Horrible tight tw@t who is more than happy to steam into my wine and food but would never invite someone over and who is always last to the bar when we go down the pub at Xmas. This despite he and his wife both being well employed in the architecture sector with no children to pay for.
He's from Yorkshire, you see.
