Getting screwed by a pre-op
Bros, most pre-ops won't screw you unless you give an indication that you want to try. Having said that, there are some who get horny and try and
force it in you.
These are in the minority and if that ever happens to you just stand your ground and refuse. Don't forget, you're the customer.
As such, most will not do it because:
1. They will get tired and may not be able to work as well.
2. They want repeat business so they'd be stupid to hurt you.
Happy bonking
