Previously I spent 8 years as a support worker with people with learning disabilities and mental health. Whilst working I was repeatedly slapped, kicked, bitten, spat at and had feces thrown at me, and on one occasion was nearly drowned! All for no more then ?8 per hour.
Now I get paid to spend time with some very nice and interesting people who give me lots of compliments, gifts, also sometimes great sex... and so far have been very polite and respectful. It doesn't compare really!
You still get the odd boundary pusher or text maniac but like everyone else as said if you don't take risks and never get complacent you should avoid the less desirable
