Vintage venting and other peeves

[AzJon]

The one thing that drives me absolutely mad, beyond any other fountain pen sin, is the over-polishing of vintage pens. Clean up some dull places, sure, but seeing a lineup of lovely vintage pens all so polished they look wet, just bugs me on a base level. There are new pens that aren't that slick. The pen is decades old, let it keep some character. To a lesser extent, this also applies to gold nibs whose patina has been thoughtlessly polished away to a squeaky-clean, gleaming gold nib.

Anyhow, what are you fountain pen peeves?
