It's not that Flores takes donations from HUE, or any other business for that matter, that's the issue or even surprising. It's the misrepresentation inherent in his appearance on Check, Please! that doesn't sit right. He gave every appearance that his recommendation of HUE was biased only from the standpoint that he loved its FOOD so much. He, of course, should have disclosed that he receives donations from the owner of HUE as well so that the viewer can at least consider the extent to which these donations may have influenced his decision to recommend a restaurant which will no doubt have an upshot in business due the episode of Check, Please! It's as if he used a show that is supposed to showcase the recommendations of "regular people" as a means for political payback. It stinks.
Of course, this raises the issue as to whether a Check, Please! participant should disclose whether, for instance, they are friends with the owners or the chef of a restaurant they recommended. It would be nice if they did, but not fatal if they didn't. I think it's distinguishable from the case of Flores because the person who may recommend a friend's restaurant presumably does so gratuitously and without any benefit to him or her. Flores has something at stake in recommending HUE.
For me, this raises another, distinct issue I have, in general, with Check, Please! when it features "famous" guests. The preamble Alpana recites in the beginning of every show is that it features the recommendations of "regular people. . . " Not only do these local celebrities get on a show ahead of many "regular people" who have been applying for years, but their opinions undoubtedly will be given greater weight by the viewing public, which again, seems to undermine the basic premise of the show.
