There must be some people that share this one

Alan has said this is a quirk and a co-worker agrees. I thought a lot of people did this, so I am not convinced it qualifies...
When I eat a sandwich on bread or toast (burgers and items on a bun do not fall under this), I eat the crust first. All around the sandwich/toast - cut or uncut and then I eat the middle and sometimes (when eating toast) I fold the middle bit in half, which sincerely makes it extra good!
Am I alone in this one??
Take care,
