When our rig needs service we call our local service center and tell them what we need. They set up an appointment for us to drop the rig off. That appointment may be a few days, or a few weeks, out due to their workload, but once we drop it off they start working on it immediately. When the service writer is taking all our information one question he asks is "When do you need it back?" - they have never missed that commmittment. If a service center just collects rigs, waiting for a service bay to open up, they will quickly run out of storage space. On the other hand, if you need to store your rig for a few months, you can give it to them for a simple job, and let them store it for you for free!
