With the postal service the uniform reg's demand a tie whenever in a long sleeve of wearing a sweater, vest or jacket but very few districts enforce that part of the code. I have heard of ad campaigns being pulled because the carriers shown were out of uniform, meaning no tie or the wrong hat and in some cases no scanner, no satchel, no ID card, no key chain.... or dog spray as the neat man cheerfully handed over a package without being tangled by the extra stuff
