Had the same observations - the wait time was the most stressful part. In Orlando office, there were around 50+ ppl there, and seeing some exiting the doors with tears of joy and smiles and some with faces like their world ended - was pretty nerve wracking. Also observing officer's personalities and some being very 'Karen' like and some super chill, it just plays mind tricks on you and I literally was sitting there for 20 minutes whispering 'please, not that Karen angry lady' or the 'mean macho officer'
Same remark on "Walmart" outfits. Just no comment.
With regard to travel - I had 10+ trips in 3 years with total of 255 days out of USA (the longest was 108 days, the first trip after covid borders opened). The officer didn't ask, just wanted to confirm if any new trips happened after sending N400. Also an interesting thing he mentioned - might be useful for anybody who has delayed oath due to name change for example -> he said, when I go to courthouse for name change and oath, I will have to update them with any new trips, arrests or changes (which are the eligibility criteria). So if you are close to a MAX limit of days out of states, make sure u don't breach the "red line" after interview but before oath, as worst case scenario - they will approve u, but then u make urself ineligible due to 'abandoning' residence status... Super rare situation I believe, but if anybody has something along those limits - u might pay attention to this.
