I see this thread closing down shortly, but the level of selfishness is beyond bounds.
Personally, I would never in a million years want to try a pair of demo earphones ever. Heck, I don't even like using my wife's airpods.
Anyway, in summary, this pandemic has taught me one thing. A significant proportion of humans are inherently selfish, self-obsessed, narcissistic and sadly don't care for their fellow people at all.
Social media has made this worse than ever through the spread of misinformation which is sadly prevalent even on this site (through posts made on this forum). I feel for the moderators that have to churn through this toffee.
