Just saw an advert for aero where they boast that it now has "32% more bubbles- absolutely free!"
If I am reading this correctly, they are telling me that it now contains more air and, since they are not announcing a bigger bar, therefore less chocolate, and we are to be overcome with gratitude that they are giving us this extra air for nothing!!
they really must think we all button up the back (or that the bubbles have gone to our heads!)
