Is it quality control at the factory and they are shipped out that way? Is it that when shipped they are damaged in transit? Are they so cheap that after a short time in use something bends? We have been in 2 local restaurants in the last 2 days that have only been open for 2 months or less and both times we got a table that wobbled. Yesterday’s was cured by 6-8 napkins folded in half. This after moving from the first spot we tried because the table there wobbled too. Tonight’s table required the handle of Donna’s knife (approx. 3/8″ thick) to steady it.
