Biased British Embassy Policies

Jamaica seems to be the only western country where all who want to renew or obtain new passports must go to the British embassy in person at designated days and hours. A check on the procedures for many countries, including those that have British embassies, uncovered that these countries do not appear to be under any strict guidelines from the British Embassy. People from these countries are instructed to simply complete the form and send it along with the required documents to the Washington DC British Embassy. So, one can only wonder why the strict guidelines are imposed for one and not for all.
