No, not dense! Just me not being clear.

Yes, one line was for business checking bags and one line for business with no checked bags.

The people in front of us had their bags weighed (carry-on bags); however, they might not have been business since they were there before we arrived and there was no line at business.

As I said, they just asked us to estimate the weight of our bags and we agreed with whatever she said LOL They DID NOT measure bags.

I should also say that we were continuing on to LHR and MIA and she printed out our BA boarding passes...so maybe that's why she was lenient? Who knows.
