Here is an interesting article from Forbes that describes some ways in which some lawfirms inflate their fees. The article is called “Grazing,” Photocopying And Other Tricks Inflate Legal Bills but the most interesting method described is charging clients for the use of conference rooms. According to the article, "some law firms ... form separate LLCs to rent out their conference rooms, turning them into profit centers instead of a cost of doing business." I have to admit, I had not heard that one before.
Thanks to the Legal Ethics forum for the link.
