French favor

An "obvious" --- i.e., easily recognizable with just a casual glance, and therefore does not need to be actually verbalized --- and comparatively-simple/minor assistive action dat someone requests merely by saying, "S'il-vous plait?"

Typical example of a French favor: Person A approaches Person B in his workshop and holds out two separate pieces of an item that have come apart, and thus need to be re-attached together with glue, one or more screws/nails, re-bending a wire fastener, etc.
Person A, a bit plaintively: "S'il-vous plait?"
Person B, immediately seeing what needs to be done, and smilingly feigning indignance: "Silver PLATES?!"
Person B then performs said simple repair, prompting Person A to gleefully hug Person B and then turn and start off again with a huge joyful grin on his face.
Person A: "Merci beaucoup!"
Person B, giving Person A an affable amused clap on the back: "Mercy buckets!"
