The difference is that in vanilla relationships/everyday lives, we are often not as aware of what we are doing or why we are doing it. In a BDSM relationship it can be very effective to let a submissive know that there has been a serious breach of trust or failure to live up to expectations about which you the dom are very disappointed. It's very very useful as a tool used sparingly to drive a lesson home firmly.

By the same token, it's very important to not overdo it, and to not respond to any infraction by being cold/aloof/distant. Being used in a more aware and more purposeful manner actually makes it used less often and for a lower amount of time. Particularly as the sub knows -exactly- why the dom is doing it, and will most likely have learned the lesson very quickly.
