Some people are just money-hungry and I don't understand the mentality. Life is an experience and sh1t happens. Sometimes it's nobody's fault.
I remember one time going for a haircut (as it happens) and I tripped over some tree roots sticking out of the pavement. I grazed my knee (sob, sob) but I got up, embarrassed, and keep going. It was my fault for not seeing them. Wasn't drunk either. I didn't think 'who can I sue for planting that tree there 60 years ago!'
(also, karma is a bitch and it'll get those chancers in the end)
