I used to work for an Australian company that produced HR software - recruitment, 360 reviews, etc. Our job application form had a fairly standard list of titles (Mr, Mrs, Miss, Mr, Dr, and maybe one or two others) that nearly all clients were happy with. However, a university asked us to add maybe 60 more, much like the list in this screenshot. Some understandable for a university (things like "Prof" or a suffix of "Ph.D.") and some... less understandable (Colonel, Lieutenant, General, Father, Capitan, Sir, The Honourable, ...)

The customer is always right... We had to add a "huge list of titles" feature flag to the system, that was only enabled for this one client. All other clients were fine with the standard list.
