Odo and Quark were probably thought by the cardassians when DS9 was under their control as that shameless couple who flirts loudly and makes out in the bus.

Middle aged cardassian housewifes would sit around and trash talk them like: “I know a shape shifter raised by those bajorans…and faregi have no concept of decorum but really must they push it in our faces??”

And meanwhile Odo is chasing Quark down the prominad accusing him of each and every single crime known to man.
