I do not mean to say that you are not entitled to your opinion, but it was a bit caustic and off-topic in the other thread. If you want your opinion to be taken as a sincere desire to improve things, I would start a generic topic about merchant etiquette or something [EDIT: which is what this thread seems to be] as opposed to making flippant comments in another thread calling out a specific merchant.
What I saw in Akkaio was Duvek running a stand next to the carpet merchant. When he was running the shop, there were a handful of weapons (not all of his inventory) displayed neatly on the tables and a book in the center with his complete list of merchandise. If I saw a bunch of scattered weapons on the ground, it would possibly annoy me as well. I thought it was very tasteful and I was thrilled that there was a merchant in Akkaio.
I personally don't have a problem with the OOC guarding logic protecting their merchandise. I figure that since they can't advertise with custom made banners and the like, that the merchandise laid out served that purpose well. This, in my opinion,is an acceptable compromise for not having a more mature in-game merchant environment. I have seen other players lay out ore for sale above Trasok's. This allows other players (potential customers) to know at a glance what type of items they are selling.
The graphics will get better and be more complete... soon (TM). I personally took the inventory laid out as just decoration, and not as the actual item for sale. In order to trade the item, the game mechanics require you to have the item in your inventory anyways.
[EDIT] If you right-click and examine the book, you can view it's pages without placing it in your inventory first.
