workout but not doing all the work?

Why do we go to the gym? Some say they want to be healthy and have a good cardiopulmonary health. Many want to be more muscular. Most want to lose some fat/weight. And how do we achieved all these? Of course by doing exercise either in the form of cardio and weight lifting to burn more calorie and to work the muscle for hypertrophy. Therefore I do not understand why some people would not bother to do the extra work in their workout by returning the equipment or weights to their proper places? Would you not think that by returning the weight to the proper rack constitute more calories burned and more work for the muscle to hypertrophy? Instead they choose to be slovenly and just leave the equipment or weights behind when they finish using it. Obviously if they are lazy and untidy in the gym, they are also like that in their day to day living. They would take the elevator instead of the stairs. They would not clean/tidy up the house as often as it needs to. This will probably explain why they are flabby or fat to begin with. So my point is this. When at the gym, tidy up after yourself cause that extra work adds up to make you burn more calorie and develop more muscle.
