Majority of the time the negative review is bullshit aswell and can easily be rectified by simple communication. Anyways mini rant over, fuck Google review system.
You know what is stupid and ridiculous as a business owner, you can do hundreds of jobs for customers that are fine no issues and not get the 5 star reviews for it. Then you can do one job that goes wrong and you are guaranteed to get a negative review.
It's like society only focusses on the negative which really impacts the overall standing of a business and the customers who get a positive experience hardly ever leave a review for that, like a 1 in 40 review conversion rate for positive.
