Silver plates?!

What you pretend-irritably toss back at present company when he "foreign languages you" with a casual request for or an acknowledgment of your assistance. (Obviously this would not be da case wif Gomez Addams, though, since he actually ENJOYS when Morticia speaks French, and so he would never feel irritable or resentful if she uttered thus to him.)

Person A, collecting small dropped objects from a pebbly beach, and passing them one-by-one to Person B to hold for him: S'il vous plait?
Person B, obligingly accepting said items from Person A, but feeling a bit disgusted at seemingly being utilized as merely a portable storage-unit: Silver plates?!
