The official answer would be no, however, depending on the store management, there is a level of freedom that is granted to their employees to "do what it takes" to ensure a repeat customer.
It is all about attitude and qualifications. Home Depot employees are trained to get involved with a customer and understand the project that they are trying to accomplish. You would be surprised how many overqualified craftsmen work there for various reasons. If you find an employee who is the "go to" guy and ask for additional help, like jigsawing, they will make it happen. This is also a good way to connect with a well-connected handyman or helper for a bigger project.
There are also many other little-known secrets in the aisles like free pipe cutting and threading, free re-keying of locks, free deck, fence, and garage designs with blueprints, etc.
Its good to get to know the store manager, they are eager to help. Their salary depends on it! Their customer satisfaction program works well and is an important part of Home Depot's philosophy.
