Well, one person appears to have been judgmental, but that's no reason to tar "the place" in the same way.
Equally, it is rather easy from the phrase "should I return it?" to place the inference that you might be intending to return it under warranty for a fault you caused.
As we haven't got much information about how it got wet, how wet it got, in what sort of water, whether it is new or second hand and so on and so forth, it's difficult to offer much advice.
For what it is worth, I got a digital camera wet and it was a write-off.
Yours may work now but may also have sustained longer term damage which causes a failure down the line.
Really, it is your camera, you need to decide what to do. If you have enough money to replace it should it fail in the future, fine. Otherwise, claim on your insurance and replace it now.
