I don't understand your rationale: you seem to suggest that his argument is weak because it's anecdotal, but you counter it with asserting that you've never had magic made for you at WDW, whereas CMs go out of their way to talk to you in Disneyland. Isn't that the same type of "weak" argument?
I must say, at first I also though JimboJones' argument was weak. Then I thought about it, and read others' posts. Certainly, it is only his personal experience, but that isn't to say that there are underlying problems causing that personal experience, which would make it more of a uniform experience also had by others.
If turnover is higher than in Florida, that would cause this type of an experience. If there is currently a strike, morale could be lower, also causing this type of an experience. If pay is lower than comparable jobs (and that difference is greater than it is in WDW), DLR can't attract the same calibre of workers, causing this type of experience. If the guests are on average "worse" than WDW's, moral could also be lower, causing this type of experience. Through in the overall "California attitude" (of both local visitors and Cast members) and I think that makes this argument fairly strong.
I'm sure there are more variables, and I'm sure there are countervailing variables in Florida. However, my bet is that the positives for working at WDW outweigh the positives for DLR.
