1) You won't like the answer.
2) WDW can't get enough people to work for them.
3) When they do, the turnover is horrendous.
4) They used to train ressie classes semi-annually.
5) They now have new ressie CM classes every six weeks.
6) Three weeks ago they graduated 70 people, and many have already left.
7) This is a very high pressure job.
8) If you don't make your hourly sales quota, you can get fired. *
9) So, combined with new people and pressure, there are errors.
* Each type of caller goes to a CM with a different hourly sales dollar quota. As an example, a frequent visitor goes to a person with a high quota, because the call should be short, due to the guest's knowledge of what they want. Conversely, a new visitor goes to a CM with a low quota, because they might be on the line for a while. That is why you are asked how many times you visit WDW whern you first call in. Quota is also why CM's don't chit-chat as much on the phone anymore. They can be written up by their supervisor for not phone selling, plus they can miss their quota by yakking instead of selling.
