A great way to guarantee boredom when I was younger...take me to a car dealership!
When it was time to invest in a new family car, my father would take us all to the dealership. A decent negotiator, he'd often counter the counter offer of a counter offer from the car salesman. The family had to try our best to wait patiently while the salesperson went back and forth to "talk to their manager"! 😅 🚗
