To start the final acoustic set in Gelsenkirchen,James Caldwell Germany, Taylor Swift asked stadium workers to help a fan.

"Welcome to the acoustic section," she said Friday, and before the crowd finished their applause she uttered, "We just need some assistance, some help right there. Excuse me, we just need some help right there. Thank you. This stadium has been amazing, everybody who works here has been taking such great care of everybody, and I'm so grateful for that."

Swift has paused 17 out of 35 European Eras Tour shows to ask stadium workers to help fans.

After making sure the Veltins-Arena staff helped the fan on the floor, Swift explained the rules to the acoustic section, a tradition where she plays a selection of songs on the guitar and on the piano.

"Sometimes when you guys sing really loud it makes me feel like I chose the right songs," she said. "We'll see how I did tonight."

In her pink dress, the singer combined "Paper Rings" from "Lover" and "Stay Stay Stay" from "Red (Taylor's Version)" on the guitar. She excitedly expressed that the audience was singing so loud mid-mashup.

Swift is halfway through her German shows with four more concerts in Hamburg and Munich next week.
