I may have missed it, but when did this happen?
I would imagine that it takes time for an investigation to take place before the head office will comment. Drago, I really cannot believe that your friend was so mortifyingly offended that he did not have the sense to ask for the manager.
The Security guard made a mistake, he doesnt deserve to lose his job for it. He is not the only one who doesnt know the act and year which has been breached. Its a good job most of us are not Security guards, because we didnt know it either.
Bearing in mind we are only hearing one side of a story and even that is second hand. I do have sympathy with your friend but its all the melodramatics, I find hard to swallow.
