There was a surprising lack of gummy candy in Geneva and I noticed there was no Haribo (my favorite brand) in the stores we visited. We tried the Bizzl mix here which was some sour fruit-flavored gummy candy, but it wasn't that sour or that fruit-flavored. It was fine, but not Haribo.
Do you know of any US airports with full grocery stores inside? I don't think I've ever seen one!
