I went to a pepsi promotional breakfast at the Aviva in Dublin a while back, have brekkie, get your pic taken with the European Cup, get a tour of the stadium, meet a pepsi football celebrity (Stephanie Roache in this case!) and they were giving out free pepsi and those Doritos flaming hot crisps.
On the way home up north, there was an accident on the motorway, and traffic was at a standstill. My brother and I thought we'd break into the Doritos. Big. Mistake. We took two or three bites, looked at each other and scrambled to find the pepsi from earlier. Still cant look at those crisps on the shelf without feeling the heat!!
