When Dr. Bashir and Quark are moving through the Jeffries tube and Quark is pushing the "heavy" box, it becomes much lighter and easier to move when Quark rushes past it to get to Bashir after his "your mother" joke. This is not a goof. Quark is so enraged at Bashir's snide joke about his Mother that his rage at Bashir gave Quark the strength to shove the crate of gold-pressed latinum aside to confront the doctor. This fall under Rule of Acquisition number 31: Never make fun of a Ferengi's Mother.
When Dax and Kira are dressing up as Vedeks, Dax pulls Kira's sash through the ring twice and fastens it twice.

But with their phasers set to stun there would be no conceivable reason for any of them to use deadly force.
