"Ma'am, I'm going to level with you - the owner of the dealership read an article that says that upselling could account for 30% of the revenue generated by the Service department if we're aggressive in pushing these services. I respect you, though, and I really don't want to sell you something you don't need. Frankly, the time it takes one of my techs to go through the motions of 're-balancing' an already balanced wheel could be much better spent on clearing out the backlog of real repair work that is the reason why we couldn't get you in here four days ago like you asked for when you set up your service appointment. Still, the owner is watching our revenue stream, and I can't afford to lose this job. So why don't you just make this easier on both of us and hand over your wallet right now?"
