Aaron arrives at his luxurious downtown hotel after a very long and tiring business trip. He walks straight to the main front desk near the entrance to start his official check-in process. The friendly receptionist verifies his reservation, asks for his ID, and hands him a digital plastic key. Aaron takes his heavy luggage, walks down the wide hallway, and enters the modern glass elevator to go up to the fifth floor. He opens the door and is very happy to see that his private room is big, bright, and completely clean. He feels a bit thirsty, so he opens the small minibar near the television to grab a cold bottle of water. Finally, he takes the phone, dials number nine, and calls room service to order a delicious hot sandwich before he goes to sleep.
