I don’t have your same concern about carry-ons. When I traveled for work a week at a time, it was nice that I could pack 5 days worth of clothes and take them with me without (usually) having to wait for 30+ minutes at the check in line and the bag carousel thereafter. The last thing you want to do when you are nearly back home after a long week of work and travel is to have to wait yet once more.
What I do take issue with is the people who queue all the way out into the hallway when boarding. Especially when they’re in the last groups and the first groups are just being called. It’s definitely worse in some airports (looking at you, CLT and ATL).
Or, all the people who immediately stand in the aisle when deboarding. Let those people who need to make their connections get up and out first.
The way people handle themselves around airline travel (particularly in the US) is one of the only places that makes me lose faith in humanity.
I visited Panama for an agricultural trip about a decade ago where we focused on coffee agriculture and production. Coincidentally, there are some coffees that blend in beans or peanuts to mellow the flavor. This is usually done for cheaper coffees that use robusto beans instead of arabica. It’s also to relieve some of the acrid taste that can develop during the drying out process if the beans are dried around animal droppings.
If you’re interested in what a mellowed coffee would taste like, I think chock full of nuts is a brand you can try in the states.
Edit: ok so I did some more research and it appears that chock full o nuts likely no longer does this, they just have typical coffee nowadays. I’ll leave it to you other internet sleuths to find a brand that does.
