Forbidden fruit, like Coors once was east of the MS. I saw similar stuff when I was in the wine business (sort of). Folks would come in with their lists.
I remember filling in on Saturday when a lady came in asking for Kendall Jackson chard cold, and when I said we didn't carry K-j, she said "What kind of wine store doesn't carry Kendall Jackson?". I sent her to the Kroger down the street.
K-J is the largest wine operation in the US now on a dollar basis and they do make some excellent wines.
