You only ever notice it somewhere you can’t undo your belt and re thread it. Most of the time it isn’t a problem but it’ll bug you, you’ll know it’s not quite right, you’ll feel your trouser’s sag a little where the belt can’t do it’s job. You just need to find somewhere to go and re thread your belt, or you could do it in the middle of a shopping centre but people tend to get a little worried when a bloke starts undoing his belt in public.
