I once saw a seagull land in the middle of an outdoor dining table at a waterfront Nandos and beat the shit out of some very upset tourists with its wings before flying off with half a plate of food
Well depends on what kind of bee lol honey bees can be friendly as long as it doesn't feel threatened or anything like that. Same with bumblebees and even carpenter bees. Only female carpenter bees can sting but males can't. So I would say bees like those don't pose a threat to us humans as long as you leave them alone and don't harm them.
