Snacks and food samples that a grocery store will serve at various locations in order to tempt the patrons into buying something they weren't planning on (pizza, chips and dip, sausage, etc.). Usually happens on the weekend.
I went to Costco the other day and filled up on store d'oeuvres.
Cabinet hardware in a kitchen or bath that doesn't actually open anything and is only there for aesthetics. Often found in front of the sink.
I grabbed the drawer handle looking for a knife, not realizing it was a dudknob.
