That would only mean that your car already has an adjustable camber screw. By default most cars comes with a straight camber screw which cannot adjust the camber without first changing the screw.

Here's where the one bad apple spoils the whole basket story comes true. For most cars out of the factory do not have adjustable camber screw. Most also have very little negative camber and will cause the tyre to wear out the outsides faster. However, some workshops take advantage of this and con the customer to change the screw all the time.
