Good on the Security guards for taking this low life down, pleading a 'lot of debt' particularly when that debt is caused by gambling/drinking/drug use that you can't afford is NO excuse for terrorising a bank employee just doing their job.
Every Robber/ Thief who stole easy money has the following
1) lot of debt
2) gambling habit
3) drug addition.
4) staying in city urban atmosphere.
5) Takes a final drastic step in this case with screw driver to rob a bank.
So far the robber was successful with even a screw driver he could get his money, however his luck ran out as he is caught.
The Trend is not going to reduce as Urban Poverty is growing in Thailand at a very fast pace.
Imagine a condition of an Covid like situation, Oil Emergency, Tsunami, Heavy rains, in this case most of us will be in the same situation.
