Not sure when the tip advisory was last updated. But there are enough warnings in the rest of the article that it may be exceeded and that there has been an increase in greedy or impatient attendants in recent years. Hence you may have a 'bad' experience has it is referenced. IMO 'should not' does not mean 'can not' or 'does not deserve' as it is the client's to begin with. But, yes greedy and impatient can be considered a bad experience.

Considering the purpose of the website, I would suggest to write a review of your experience with said attendants either good or bad, and other clients can choose who they wish to see based on said reviews. As with most reviews one person's experience is different from another person as well as we don't always hear both sides of a review good or bad.
