£700 for first 12 month service!!!!

my 620 is going in for its first service on sturday and i asked how much they thought it would cost.
£140 rear tyre
£75 to fit scottoiler
£485 for my service and they are not even changing the belts!!!

I had a 12000 mile service on ruths inc blet change and pads and value stuff a few months ago and that only cost £360...so why is my new bike costing so bloody much?

Has anyone else had a 12 month service on a new 620 with say 5000 miles on it , if so how much did it cost you?

Please help i think i'll have to sell Ruth on e-bay to pay for it!
