machine nicks in the rim are caused by the tire mounting machine. It has a steel arm that rides the OD of the rim in order to stretch the tire bead over the rim.
This steel arm being forced against and mving over the aluminum rim will causr galling or a slight surface deformation right along the immediate edge of the bead seat. It will hardly be noticable but is there.
The manager is right he has no control over this since that is the only method of installing the tire. However, it can be reduced by using a lubricant, When I used to change tires in high school I used soapy water, its amazing how well it lubricates.
