Not the establishments issue.
Just for the record, I only "bashed" them in this post about my general discomfort based on the rasperries. - For the most part I have tried to stick to the issue, which was trying to justify the sale of them. If you can successfully explain this, there is no issue.
BTW, From a pure business perspective they are making a mistake IMHO. This leads me to believe that they actually don't realize.. I guess in their other locations these products sell well...
