Make sure that they remove the pads on (at least) that caliper and check for
contamination (i.e. a rock). If you can just barely see and feel the
groove, it may not be anything to worry about. If it is a little deeper,
the rotors can be "turned" (metal shaved off) to make them flat again. If
the rotors are turned, replace the pads. If there is something embedded in
the pads, replace the pads. If the pads are no longer flat or an even depth
all the way across their surface, replace the pads.

Pads are MUCH cheaper than rotors. If there is any doubt as to if the
rotors should be turned (e.g. the dealer gives you the option) don't turn
them.

I've never had a dealer give me the option of turning the rotors.It's part
of their brake job.Perhaps they would not warranty their work if you have
them do it differently than their standard way.
(plus they want to sell rotors)

If the grooves are too deep,you will need new rotors.There's only so much
that can be removed from a rotor.Once down to a specified thickness,the
rotor must be replaced.
