RileyRyder, I think it's fair for you to ask not to be brought into the discussion. This is a word of mouth industry and folk can misunderstand posts. This is your livelihood and you have a right to protect your name.
In regards to Riley Rage; Tattoo's are her thing. I'm not certain why anyone would book with her if they didn't like tatttoo's but it is what it is.
As far as 'mechanical'...everyone has a bad day and not everyone clicks. It's a job. I'm mechanical at my job too. That being said, I DO understand how it can be disappointing when things don't live up to expectations. I've seen Riley Rage, she's a nice woman, service was good, she was on time for me, but that was my experience. Yours was different.
In my opinion, and it's only my opinion, we should, for the most part unless there is something serious happening (theft, violence, harassment, etc), error on the side of caution and give the providers a break. It's not an easy job. I'm ridiculously ugly and providers still accept me. So when we flame providers it can have serious effects on them.
At the end of the day, do as you will, but kindness never hurt anyone.
