Sorry but any able bodied person who would do this is a price of $#@×. Those us with actual disabilities who need this assistance often sit at gates while we wait for someone to be freed up. Their priorities are boarding and unloading. So if they are short handed we can be unloaded and wait at that gate while they unload others. My flight weds it was two guys at Dallas who unloaded 6 passengers. I was left at the gate till the others were transferred as I had the longest layover but was getting very nervous I was going to miss my flight. Also its almost impossible to load if the plane is already full due to obstacles. Unless you the same aholes who think it's ok to park in handicap spots please rethink you abuse of a system that exists due to true need.
