I used to work for a wheelchair rental company and I'd loosen the wheels and brakes
Are you joking? Why would you loosen the wheels and brakes?
I needed their extra business.
What you did was despicable. You put those people in danger for personal gain. You should stop that and apologize.
The company did not complain.
It's horrible that you would sabotage people's wheelchairs for prophet. You probably injured a lot of people.
