Need a bit of help/advice....
After a recent service various fairing screws/bolts/nuts have gone missing

Anyway, one's that are missing are:
1 from underside of right rear fairing next to tail light.
1 from left upper fairing
1 from left side tail fairing, silver screw below seat
Also the screw at the front of the airbox cover is there but not screwed into anything???
The bloke who did the service did admit to the screws/clips that join both front fairings together (belly pan) going missing and has bodged them together with diffeent bits.
2 months have past since the service, with the dodgy weather and going on holiday, today has been the first time the bike has been washed since and I've noticed this bits missing.
So, firstly do I go back to the bloke who serviced the bike and ask if he knows what happened to them ( friend of the family, does the work cheap and is usually of the very highest standard, has done loads of work in the past for me trouble free )
Secondly, does anyone know if Kawasaki can supply these bits individually and any idea what they cost.
My local Kawaski dealer is Anchor in Finedon, would asking nicely get me the bits off the workshop floor.
Thanks in advance for any help/advice!!!
