In 2373, Morn hit Quark with a barstool after Quark suggested that the space station would likely be the Dominion's first target in a full-scale assault against the Federation and everyone on board would likely perish.

In 2374, Quark installed new backless barstools, much to the frustration of Constable Odo, who ordered him to revert to the old ones by the end of the day, citing Station regulation twenty five sixty two, paragraph four. Later, he complied unwillingly, accusing the Changeling of stifling his creativity, which caused Odo to remark that "Only you would consider barstools to be a form of artistic expression.".
