You just have to keep in mind not everyone can walk up to their hives, open it up and not have bees bother them. Better to wear a veil than not in my opinion. My bees are very gentle most of the time, but you never know. One day before I even got within 10ft of the hive I had 2-3 bees on my face. Someone had pelted the hive with dirt clods a couple days prior, they were still upset I guess. Two days later, back to normal where I could observe the hive w/o issue. As Keth says, smoke is a good tool to manage the hive when putting it back together. I use it to keep them inside when I open it up as well. Just a quick puff. I don't mind my bees all looking at me, they generally get out of the way when I grab the frames and show no interest in stinging my hands. But you never know, u get a new queen, might get meaner at any time.
