Nowadays, in many public spaces, security will flag you and ask for a permit for photography when you are seen using a tripod. You have a tripod therefore you must be a professional. Where is your permit?

Either that or they kick you out immediately from the premises because you have one.

Photos taken at North Ave. Beach at sunrise on April 8, 2017. In the pictures are my tripod-bearing photowalk buddies, Mark, Tim and Michelle.
