I asked for coolant flush and spark plug replacement (overdue on my car). The service contact recommended wiper change and fuel filter replacement also, which were noted as problems after the complimentary overall vehicle check was completed. I then authorized those replacements as well. I appreciate the overall vehicle check, but I think they should make it clear up front that it's at no added charge.... I initially thought they were charging more for something I hadn't asked for. However, I've found over the years of using the company that they are honest, thorough and do a good job.
