Factual error: When Wayne and Garth are driving to the Alice Cooper concert in Wisconsin, they pass palm trees while driving the expressway from Chicago. There are no palm trees on any expressway in Illinois or Wisconsin. (00:57:00)
Factual error: In some of the shots of the band playing, it is very obvious that Cassandra isn't playing her bass correctly. Particularly in the basement performance, where she sometimes doesn't even move her arms at all while singing. (00:13:25)
Factual error: When Wayne and Garth drive to Milwaukee, they leave Chicago, the sign reads Wilson Ave, when they announce their arrival - a very similar shot pops up reading Wilson Ave.
Factual error: When they are driving around listening to Bohemian Rhapsody in Garth's car they are supposedly in Aurora, IL but Cermak Plaza is in Berwyn, Satchel's is in Cicero and the White Castle is in Lyons. All these towns are an hour away from Aurora.
Answer: It was just establishing that Wayne and his crew were friendly with Officer Koharski. They cut their conversation short because they were afraid Phil was about to throw up and needed to get him a cup of coffee.

Before Phil gets sick, they're just having a conversation. After it cuts from Phil, Koharski is suddenly holding a quarter in between his fingers. There seems to be a scene cut before they see Phil get sick to explain where the quarter came from. (Like if I had to guess, does Koharski pull out the quarter to show what he found in the cavity search?) That's what the question is asking, not is there a scene cut after Phil gets sick to explain why Koharski just walks away.
