Sorry to derail your wasp theory, but these were honey bees, living in those big flat box hives like we've probably all seen on TV or in the movies. 😋
I was definitely in their space, taking a tinkle, lol, but not on purpose. It's an old neglected business, with falling roofs and overgrown weeds.
What surprised me was, I only got stung once. I must not have seemed very threatening, there were definitely backup bees around, too. 😲🤔
