No. 2 – what you saw at the airport reminds me of my experiences at Chicago airport a few years ago, when I, in excruciating, paralyzing pain asked for help to lift my suitcase off the belt, but was instead met by a similar treatment. I sank to my knees and sobbed in despair (still no help though, just a hateful face)! By the way, I’ve NEVER met polite and friendly officials at Chicago airport (except for the porters outside the building). It really is a disgrace that what you describe is going on.

No. 3 – A host of passengers, many of which – should be many of whom….

The sentence starting “The officers, who emphatically did NOT behave in a polite and helpful manner and yelled loudly etc. does not have a “predicate”, in other words it’s just sort of hanging there. There needs to be a follow-up to “the officers” – here’s what I mean:
“The officers, who … did NOT behave in a polite and helpful manner… if you remove “and”… yelled loudly….. which gives it the required “follow up”, i. e, predicate.

Does this remind you of something? (like late, late nights with you writing school reports due the next morning, and me picking at them with my red pen at the concluson of each page).
