Integrating valet service with POS

We recently set up our system to include communication with the valet and I was wondering what others out there thought about this?...
By the server asking for the valet ticket when they return to the table to collect payment and entering the ticket # at the POS, the valet receives notification to retrieve the customers car.

With only a few extra touches at the POS terminal, the servers are moving the tables faster upon payment and the feedback from the customers has been appreciative of the added service.

The cost to add this option was only about $300. This particular restaurant has been happy with the results, by I was wondering if anyone else out there is doing this with success as well?

Thanks in advance for any feedback.
