The gym guide smiled at Sato. He said, "Hello! I'm Clyde, the guide for Trainers who challenge Pokémon Gyms. Thank you for taking on the Gym! Take this to commemorate your debut! Pokémon Gyms are facilities for testing Trainers' abilities! Put simply, if you can defeat the Gym Leader, it means you're a really good Trainer! If you run out of Pokémon that can fight during a Pokémon battle, you lose! So having a lot of Pokémon with you might work to your advantage!"
His speech gives this feeling of "scripted". Much like how guards in fast food restaurant say, "Come again."
