I don't interact directly with a lot of CMs when I'm there, but grooming standards like facial hair, tattoos, long hair on people that "shouldn't have it" are not concerns for me at all. The only experiences I remember and carry with me are positive. One in particular that stands out... I was at the MNSSHP near the end of August 2023 and I had a virtual queue called for Tron but I was by BTMRR and Boo to You was going and I couldn't find a way to actually get to Tomorrowland. One very kind CM actually walked me to the hub so I could get the rest of the way, which took 5-10 minutes of her time and took her completely away from where she was stationed. Only after she walked away did I think to submit a compliment for her and I didn't remember her name. Cut to this year, again at a MNSSHP in late August. I'm standing in line for PPF and the woman at the end of the line says "do you come here often? You look familiar and I think we've talked before." In the moment it didn't ring any bells and I found it unlikely she would recognize me because I only travel to WDW once every year or two. But as I was riding my pirate ship I thought of that interaction from the previous year so when I got off the ride I walked over to her and asked if that was her, and it was! I took a picture of her nametag and put in a compliment for her. It was so neat to be able to retroactively do what little bit I could to "reward" her for going above and beyond almost a year later. Also this year I was there over my birthday and I got a birthday button for my first day in each park and the number of "Happy Birthday"s I received was overwhelming! It was such a great experience.
For almost every one of us, we expect the employees to recognize that our visit to the parks is a special time for us. And in my experience (which I fully recognize is not yours and yours could be different), most of them do and those that don't at least don't actively make my visit worse. But to expect CMs, who have personal lives and good and bad days like we all do, to give their all to an employer who it seems trains them less than they used to and appears to value them less and less so they can reward shareholders more and more, is unfair and unrealistic. Every interaction is a two-way street and I try to keep that in my mind whenever I interact with them. It's our responsibility as much as theirs to be as gracious as we can in out interactions, and if you think about it, we are guests in their workplace so arguable owe it to them.
