A brake lathe takes same space as a chair and a shop press is even smaller, a screwjack set of bearing cups is stored in a space of 15x8x4 inches, now if mechanics are still piling tools and parts on the floor and dont beleive shelves have been invented then its their fault for not being creative with space management.
The issue is that customers look for shops which are tiny and unkept hoping to get a “cheaper deal” assuming the properly setup and equipped shop will be someone who is “khaal khenchta hai”
Just like homeowners go looking for carpenters and electricians at markets with people sitting on sidewalks (newer era is whatsapp references etc) - without counting the most important factor of “quality of workmanship”
