Pet Peeve - Do you or don't you?

[Aquattro]

Anytime I get a new coral or frag, I cut it off the base and mount it directly to the rock. It drives me to see people puttying frag plugs, or worse, chunks of maricultured bases to their rock work. Even after the coral encrusts, I can see the outline of the plug/base.
Who does it which way and why?
