"All"? More like a small minority.
And so is the percentage on DDMS of DDF. The point is everyone loves a good deal. The problem is what happens when ppl don't have where to sit.
I don't think anyone is apologizing. I'm saying that people might be too embarrassed in that situation to just stand up.
While your probably right that doesn't mean that it's a valid excuse.
Personally I buy a seat for all my kids for safety and convenience reasons, but CH is clearly another reason to do so.
I actually never buy a seat as my babies never sit nicely in the Car seat...
