And I basically agree with Peterius that bringing the concept of a "request" into the rules for a tournament or here is a clumsy way of both speaking and (more importantly) perceiving what is happening.
Besides, people don't usually say at the table - please, pass the salt. Or please, pay for the fare.
They say - pass the salt, please. Or pay for the fare, please. In these situations, there isn't even the word "прошу."
It also requires certain neurons to connect in a certain way in the head to see a "request" in this. Which won't happen in every head.
