I once worked on a UK e-commerce site. The existing user registration form had a title field. The previous engineer had listed a few titles in the requirements, and the longest he came up with were Colonel, General, Admiral and Viscount, so he set the width as 8. I got assigned the bug when one of the only two Archbishops in Britain tried to open an account. Luckily, Field Marshal has slipped from normal use in the British military, but he should have also noticed Brigadier, Commodore, Rear Admiral, Vice Admiral and perhaps Ambassador. I guess Second Lieutenant or Sergeant Major aren't pompous enough to offer their titles to buy s***f on the internet.
