I saw exactly that on the conveyor in front of me last week: several 2-litre bottles of a cola drink, loads of crisps, loads of chocolate and some pasties. When I looked, the couple (and their two children) were gigantic. But they did seem very happy, so who am I to judge? They don't affect me or any part of my life. But actually, oh yes, they did stink very bad too, as though they hadn't washed for some time. That's not anything to do with size though; I've been treated to stinkiness from skinny people too and every size in between. I guess the stinky issue should be a new thread.
