After the small-ish company I worked for was bought by $ENGINEERING_MEGACORP, an integration program was promptly launched, during which numerous committees were formed to evaluate all business processes and take the best parts of both companies' DNA.
After thorough evaluation, it so happened that the existing practices of the megacorp was adopted without any modifications.
The next day, the office shredder had been labelled 'Suggestion box'.
Poor sods from head office tried to remove the sign, only to find some miscreant had mixed glass dust in the glue used to affix the nicely engraved sign onto the shredder, making removing it kind of difficult. End result being we got a new shredder.
The spare sign which was engraved just in case now adorns the outhouse at my cottage in the woods.
