Here in Philippines its expected for you to leave it be at the parking spot. Someone from the Mall/ Supermarket management will return it. There is someone doing a dedicated job for it. Not sure if it’s a bad courtesy in here. But you would be probably robbing someone’s job for it. The same is also with going up and down with elevators. Though not common in office buildings. I guess this probably started in USA as a cost saving idea for the companies, similar to how they convince us that jaywalking is bad and not tipping is bad.
