Korean security is a hell of alot of bark and no bite...
Basically, lots of security gaurds....who usually are the following
A: old dude security guards who sleep on the job and generally let you do whatever the hell you want...possibly wrecked on Soju..
B
kinny young dude in a suit...trying to look cool to score some chicks
C: Fat dude in suit...this guy is the heavy...Porbaly has low self-esteem...
More cameras than a busy intersection in London...they love CCTV...and proudly advertise this fact publically...I don't think anobody is watching these intently other than the old guy who sits at the front desk watching tv and drinking soju or sleeping or playing card games or etc....
Tiny ass decorative fences...koreans usually jump these all the times...including adults.
THEY do however, Lock doors from the Inside half of the time with a rope lock...good luck breaking into that....good thing they usually leave the rear unlocked or poorly guarded.
