You should also consider that both punters and provides have bad days and a poor review is no guarantee of poor service any more than a good revue is a guarantee of good service. I'm sure many on here would confirm that they've had different experiences with the same girl, and sometimes you buy food from M&S and it's not as good as it was the last time you had it. For the most, particularly if you read and understand the reviews, what is said and what isn't said, that you appreciate that different punters will have different expectations, read the revues, ask the right questions before booking then you'll have far fewer disappointments than triumphs.
