I think Whogivesa was writing about "baggage" as opposed to "bags"
As Biscuit Chucker knows, we regularly get people with ridiculously oversized, or over their maximum number of pieces allowed as carry on.
You need to be sensible about it, but I'm always happy for offending pax to remain behind with their excess baggage if they aren't prepared to compromise with me.
I'm still yet to leave anyone behind
You just need to explain why the limit is there......
