Angels - like all other intelligent creatures - were designed to render worship to God, not to receive worship themselves. In fact, in every case in Scripture, whenever angels are offered any form of worship, they always rebuke the worshiper and redirect all worship to God alone.
Nowhere does Scripture encourage us to have an angel-fetish, or to look for evidence of angels in everyday life... [Furthermore] biblical appearances of angels - unlike those of popular lore - often cause trauma and great fear.
