This is not a normal occurrence, this is not something that should be swept under the rug. Just a few milliseconds earlier I listed the directory and found files A, B, and C. I successfully deleted A, and then B. Turns one someone else deleted C in the meantime.

That is *not normal*. That should be delivered upstairs to let them deal with it. Just because our job happens to be done for us doesn't mean that we should continue along our merry way.
