Safety First !
Just to share my personal experience today (deleted the pic because forgot to censor the face of people in it)
This is a generic post meant as warning and to enhance safety for all. Can't be sure who are those people standing there.
It comes down to this... When you go see an FL, be vigilant, check your surroundings and if anything feels off, trust your gut and reschedule your booking.
Don't let your small brain overrule your big brain 
Stay safe all,
J
