a lot of people i met stay away from those mexico coke glass bottles simply because they don't trust the water quality in mexico or sanitation though I'm not sure about it myself
also the bottle caps on those coke glass bottles aren't hard to open. Over half of the time you can just use your shirt as a cloth/rag to cover and grip around the cap and twist it off.
as for the table /key trick they aint doing it right....gotta get the key tooth to hook into the folded ridges of the cap to pull out gradually
And yes unfortunately while stores sell stuff, they don't have the proper tools or can't use their brains to think of a way to help....
