When contestants on Wheel of Fortune and Jeopardy say please after each turn.
"I'll take a C, please." Ok. Maybe for the first turn but after that it should just be obvious. Kind of like when people sneeze a lot. One or two sneezes, I'll say bless you. After that, it is just clear that I meant bless for you for the entire duration of the sneezes.
Same with Jeopardy. There are a lot of clues people and time is a ticking. No need for the please.
