Metropolis lies as hell so do not take their quote for granted.
In regards of your service, anything relating to chain/sprocket/pads is not part of service it is consumables like tyres and as many said I am surprised that chain needed changing so quickly.
In regards of plugs I never go over 7k barier on them, do not bother cleaning and re-gapping.
