I feel it's pointless, maybe if anyone here sat down to an actual meal around a table and ate that way, it might make sense, but we don't.. We eat where we usually sit during the rest of the time (me at my computer, wife at the food of the bed [where her computer is] mother-in-law on her bed in her bedroom, etc) besides the 'presentation' is going to be destroyed after the first few seconds anyways.
I honestly find it pretentious. You can make a good presentation without the garnish.
