A group of scammers/fraudsters whose duty it is to steal from the normal working-class public, and fail to reach their delivery times/dates. They are sometimes dubbed the 'Royal FAIL/Royal Snail' due to their lack of care and accuracy in the matter. They appear to be getting worse by the day, it's highly recommended that you don't put your trust and faith into them, as they'll grind you to the ground.

Sue: Well I sent it out with the Royal Mail 5 days ago...
Bob: No, sorry.
