Do not open on Saturdays, this is when the homeowners and hobbyists are out and about. If the locals know you are open you will get a never ending stream of broken bicycle parts, broken $19.00 beach chairs, door handles, broken wrought and cast iron patio furniture, kitchen appliance parts, truck ladder racks, car roof top kayak and bicycle racks, home plumbing fixtures, fireplace grates and guards, lawn sprinklers, lawn mowers, floor lamps, reclining chairs, BBQ grills, ceiling fans, floor fans, garage door opener components and so on, most all of these people want you to make a part to repair something that they bought simply for it's low price, you can not do so. Just Say No
