Well.... on the street, so to speak, yes.

Twice.
Once I was followed by super-persistent fan. It was slightly scary and my husband had to ask him to leave me alone. I have seen him around since then, and he always tries to sort of follow and engage me but I am spooked now!

Another time I was with kids at a kids activity center, and a dad approached me. It was kinda, weird but neat. He was polite, and was discreet)
