The service people are spouting nonsense. If you are getting 15 km/l, why should it come down to 12 and continue from there?
One thing you should bear in mind is that fuel mileage is rather subjective and can be due to various factors. Even simple conditions such as low tire pressure, overfilling of engine, traffic condition oil etc can result in differences.
