I’m working on a method for something at work and submitted it for review to make sure it was okay.  It was approved, sent to the UK for review, and sent back with all the o’s changed to ou’s where British dictates (colour, armour, etc.)  The document was then reviewed again, the spellings were changed and resubmitted and then promptly rejected by the UK team, changed and then returned to the US team that reapplied the previous changes.  Bureaucracy may be the secret to finding a perpetual motion machine.
