The above frightened me; thought they'd added beans into the normal full Heathrow breakfast, and I hate them so very much. Their ability to seep is just... no.
They do appear to be part of the Gatwick one, but I'm now wondering if for some reason the last morning flight I had from there (to Bordeaux, and operated by DAT) for some reason got their version of this. Because I don't think it had bacon, either.
