Even if he/ she wanna search your bag, they should still seek your approval 1st and it should be you or your GF to take out things from your bag to let them see/ check and they should never lay thier hands into your bag as it's oso as good as stealing!
Given me, if they wanna make a big hoha, call the police in and let them settle it! I will boycott the LFS since it's not the only one ard!
Anyway, thanks for sharing with us your incident with such "ah beng" style LFS!
