Vlogging in public is no easy task. I've dabbled in it a bit and have honestly had some similar experiences to you. Once you get over the weirdness of talking to a camera with other people around- it's really more the interactions that happen afterwards that are sometimes not as fun. For me, I think it depends if i'm in the interactive mood or not. I've vlogged in public a few times and had people just come up and start asking questions in the middle of filming - which is a little rude... in my opinion.

Sometimes it's just fun to switch up the background though and give the video a little different energy. :)

Enjoy your coffee!
