When I was in school, I never took my bag or phones to school during examination because of cases like this. I have heard and seen many of this then and for me to not be a victim, I would have read enough at home while I go to school with my pen and other writing materials. In fact, I don't take money because I know I won't be staying long in school.
For the bank case, I can never give my money to anyone in the bank even if it's a security or personnel. The people really made a big mistake. Sorry for them though but they have learnt their lessons in the hard way.
A big and painful lesson at that. Thanks for engaging
