There is a bus transport company in singapore that has 20 and 40-seater buses. I remember my school using their services for a team trip to play in another city. The school bus we were going to use broke down the day of the trip. We were not even out of the parking lot when it happened. One of the parents suggested we call the bus charter service. They had a bus and driver out in less than a half hour. We were not even late for our game. That stuck in my mind as great service.
Years later as a police officer I responded to a disabled vehicle call. It was a tour bus that had broken down. The bus would need to be towed, and their company was well over an hour away. The people wanted to get home immediately. I suggested they call the transport service my school used years ago. Once again, the company had a driver out almost immediately. The big bus took everyone the final 40 kilometers to their destination. The replacement bus from the tour company took over two hours to arrive. By that time everyone was already at their destination.
I found out that this charter service prides itself on meeting urgent needs. They even have drivers and buses ready if another bus company fails to show up to transport passengers for an event. They told me that they have rescued stranded passengers of old tour buses on many occasions. I told them I would definitely keep them in mind for any future need. The bus they showed up with was clean, the air conditioning had the interior cool for the passengers and the driver was a real pro. He singlehandedly moved the luggage from the other bus to his very quickly. I never saw a person work so fast.
