Perhaps something like this: participant & confederate are waiting at the bus stop. Guy with chips approaches them in a hurry and says “I’m late for my ride to the airport, does someone want my chips?” Participant & confederate both say that they do and move closer to the guy with chips (confederate attempts to act similarly to the participant). Guy with chips hands them all to the participant (who is perhaps slightly closer), says “here, take them—you can share them with the other guy if you want”, and rushes off.
That way the confederate is someone who has been through essentially the same experience as the participant up until the moment the participant was handed the chips. He is not just some guy who happened to be standing nearby.
problem: this introduces social pressure and possible consequences( this person might recognize you in future and penalize you in the same way), part of the dictator game is that you don’t have to look the person who you’re splitting the cash with in the eye.
