Once when i picked up my bike I asked the dealer if they test rode it after the work was done. They looked at me like it was a stupid question and assured me they did.
When I rode away on the bike it was OBVIOUS right away that the brakes weren't working properly. More than once I wish the dealer had test-ridden the bike before telling me is was ready.
So...I would love to have them take an extended test ride after service work, even an oil change.
