Somewhat realted to this thread....
A couple of sessions ago, my players ran afoul of some Metallivore Grick. (template from Book of Templates 3.5 that eats metal as does a rust monster, except it has a breath weapon that affects metal items.) On the pc's approach, I had one of the gricks breathe a "warning" blast onto the metal floor, basically to display their capabilties, and also to try and convey that the gricks were more afraid of them than otherwise.
The pcs still advanced, and one of them found out, the hard way, that he should've left well enough alone. He only lost his armor. I didn't get any complaints out of character. He was still effective for the rest of the adventure.
