The party of the first part (andy) and the party of the second part (customer) have entered into an open ended verbal agreement. Where as the party of the second part has entrusted the party of the first part with possession of property to be serviced or repaired. And where as the party of the second part has not made any clear indication or given an ETA for retrieval of said property. And where as there has been no legal agreement concerning this detail (either verbal or written). It is to the discretion of the party of the first part that the decision lies.
Once a reasonable amount of time has passed (based on the value and size of the property, its ability to be stored convieniently, and a reasonably calculated storage fee). Ownership of said property can be shifted guiltlessly to the party of the first part (which any Buddhist knows is imposable).
