I like Margrit, but maybe I have a lot higher tolerance of interviews with people who don't speak English as a first language. Its easy to see that she's translating in her head. She might be more successful being herself more and letting the words come out instead of trying to sound more intelligent in using a second language.
I listen to a lot of NPR and BBC so to me she's just interesting and doing an excellent job.
I do agree, if they are scamming us, they aren't making much for all their trouble. Especially actually getting product into COSTCO.
