I owned a guesthouse many years ago and one of the things we offered was motorbike rental. It took merely half a year or so before the 3 motorbikes we offered for rent were scratched all to hell along with the people who rented them. I didn't rip anyone off on the repairs but I wonder what the statistics are on people that rent them compared to the amount of people that crash them or at least lay them down a bit.
As the owner of that guesthouse I was extremely common for at least one person who was staying there to be covered in bandages from exactly this sort of injury.
I crashed a motorcycle once in Thailand and was wearing stupid clothes and my road rash was so bad that I could see my knee bones and bones in my toes. I also broke 3 bones in my ankle / foot. This wasn't a scooter though, this was an 800 CC Honda Steed motorcycle. Looking back, it is completely stupid that I decided to ride that thing with a swimsuit and flip flops on and it resulted in me being sofa-bound for 2 months. Lesson learned for sure.
