Yay Courier - Mission Details:

Yay Courier, along with Big Smoke's Cash, is one of the two side missions in Grand Theft Auto: San Andreas dealing with the Loco Syndicate's Drug Dealing operation.

The mission is triggered by a phone call from Cesar Vialpando every Wednesday and Saturday, but only between the missions King In Exile and Yay Ka-Boom-Boom. Because this mission is restricted to a specific time period in the story, it is not required for100% Completion.

In the mission, the player has to chase an off-roading courier riding a Sanchez carrying a backpack full of drugs. To complete the mission, the player must kill the courier and recover the backpack, but shooting the courier will cause the backpack to leak its drug content. The mission's payout depends on the amount of drugs remaining in it, for a maximum of $2000 per completion.

It is important to note that CJ will only receive the phone call for this mission if he is on foot.
