No, just experienced over forty odd years.
The other week I had some 'toast' made from a piece of something which came from a plastic bag and labelled 'Hovis', spread with something greasy which was contained in a plastic tub and coated with a yellow, jelly-like, sweet and otherwise flavourless substancefrom a jar labelled Olde Fashioned Marmalade - or something of that ilk.
Two bites from said anointed piece of whatever it was convinced me that it certainly wasn't bread as I know it. As for the 'marmalade' element - blech.
