I remember a few years back going to that In N Out after a day at the park. There was a table of Space Mountain CM's in full costume complaining about guests for the day.
Which is well within their right to do- but it makes me wish Disney still forced every CM to check in/out their costume every shift and change on property. When I went through traditions a year ago, the trainer said that you just have to take off your nametag when not at work, since that's what 'distinguishes you as a Disneyland employee to the public'... like, no- it's the iconic costumes that anyone in the area would recognize.
While working there it became obvious that a day at Disneyland is just to darn complicated now for those who don't follow everything to understand. Fastpass, Maxpass, Dining packages, EMH, mobile apps, etc.. and that the entry level CM's eventually get tired of trying to explain all this to guests.
