If people want to continue receiving their new engines it might be better not to post a phone number. Probably better to make service contacts via e-mail to free up phone time and provide a lasting record of the service or parts required and eliminate the need for paper notes and trenscriptions that can easily be misplaced. Voice conversations can go on a very long time beyond that needed to relate the need for parts or service.

One phone call is not a big deal but they won't stop at one. More likely in the number of a hundred or more at 30 minutes or more each. That's a lot of productivity lost to social B.S.
