I have a similar car (though Classic trim rather than Avantgarde), and to be honest I can't think of anything that might cause it... the A-Service is just an oil and filter change. They don't even take the wheels off.
Have they done any 'additional' items - e.g. Air Filter, Fuel Filter, Spark Plugs, Discs and Pads, etc?
If the changed any of the above then maybe they got something wrong - e.g. wrong type of spark plugs, or the brakes are binding/rubbing... but other than that I can't think of anything on an A-service that can cause this.
Perhaps it is a coincidence? Have the Air Filter, Fuel Filter, and Spark Plugs been changed as per the MB schedule, i.e. every 4 years?

Good one. Didn't think of that...
...and if they filled it up above the min mark on the dipstick?

I can't imagine oil viscosity making any noticeable difference and if it was too full the the high oil warning would be on.
Maybe they've switched the auto box from comfort to sport!
Most obvious thing would be a leak somewhere - but is the fuel filter changed at this age/mileage on a petrol/

The C180K ain't got one...
Only a low oil level warning.
The privilege of high oil level warning is reserved for the dipstick-less diesels (and *some* petrols).
While petrol engines won't exactly have fun if they had too much oil, unlike diesels, they won't commit instant suicide either.
