NC/NS, NCNS
No Call / No Show. See also no-show.
No-show
When an ASP or hobbyist doesn't show up for an appointment and has not contacted the other party in advance to cancel or warn of problems in making the appointment. A very annoying and, unfortunately, too common occurrence in the hobby. When the offending party doesn't call afterwards to offer an explanation and/or apology the situation is referred to as a No-Show/No-Call (NS/NC) and is considered an even more egregious offense.
