What is it with Subaru guys and riding clutches?

There is a shop next door to my work and it is down right excruciating to listen to them moving cars around. WHOM_WHOM_WHOM_WHOM trying to back up, never releasing the clutch or rev it to 3k then ride the hell out of it to move!

Day in and day out, riding clutches all day long. Do none of these guys know how to drive a stick? Do they think it sounds “cool”? Do they enjoy replacing clutches yearly? What is the point?!?!?!?!
