Are there no builders that also thoroughly play in their creations?

I playtest my builds (unless I forget). I use moveobjects but mostly to place clutter (not too much or the lot can get laggy).
For restaurants, I try to keep the number of tables low (the last restaurant I made has 7 or 8 tables), and to not place them too close from one another.

Also if people don’t leave comments to tell me when there’s a problem, (even if you playtest, you can miss stuff) I can’t always know it and fix it.
