The scheduler everyone is talking about seems to have a split personality. I had very pleasant dealings with her recently on a fairly complex shop in which not all of the instructions were clear. She was very helpful, and we had professional as well as friendly email communications.
However, several months ago, I had to cancel a shop due to my son's significant health condition. (He was OK one day and not the next; it was unexpected, as we thought he was past the worst of it.) She was OK about canceling it (as in, didn't fuss about it), but gave me a 1.... Maybe that was justified; I don't know, but I don't like the tone of some of her eblasts out to all shoppers, and many years ago had some less-than-pleasant dealings with her.
I had a similar situation with another MSC earlier this year in that I had to cancel two out-of-town shops I'd piggybacked on to each other, and there were no "markdowns." My son had had a TBI and had a relapse of symptoms requiring an emergency visit to the specialist, and I truly appreciated the MSC's understanding. They were great about it.
OTOH, one of the other schedulers mentioned in this thread as highly regarded was quite curt with me over a shop issue recently and basically refused to explain the ambiguous shop guidelines. I was left to "figger it out" on my own.
I guess schedulers have both good days and bad, like shoppers. Some seem to be chronically rude, some usually polite and professional. But there are exceptions to everything.
