If I stay at a hotel and the breakfast is bammer, I will at least eat some cereal and some fruit. Same thing if I am staying at someone's pad, like I remember in Stockholm I ate cereal, berries and yogurt every morning because I didn't want any funky cold cuts.

I keep some at the house but I'd say I eat it a bowl every other week. If other people didn't eat it, it would go stale. When I was a kid I pretty much lived on cereal.
