I've been living in Prague for basically two years. Generally speaking, the quality of food available in grocery stores is low.
In the past two years, on two separate occasions, I have found stones (or more properly – pebbles) in items I've purchased.
The first incident was with a package of raisins. There were raisins in the package. It also contained seeds, stems, twigs, and then on one day, I bit down into a hard pebble (the same size as the one pictured below).
Now I no longer buy this brand of anything:
fuck these raisins
Main message: Fuck this noise.
I think I'll just drink beer and eat bananas.
