My gf does it, and she is getting worse! Honestly, it doesn't bother me but I do sometimes find myself watching her eat, which annoys her 
For instance, a Sunday roast will be eaten foodstuff by foodstuff, nothing mixed. A multi layered chocolate bar, will have its chocolate stripped off the top, then each layer eaten individually. A corned beef pastie gets its pastry taken off the top, then the filling eaten, then the bottom layer of pastry and so on for pretty much any kind of meal you can easily take apart.
The weird thing is, something like curry she will mix in and eat together. It's obviously an OCD thing over certain foods which can be easily split.
So, is my gf alone in the universe doing this or anyone else want to fess up to this strange eating practice?
