Questions for discussion:
Why would a gambler adventure in such a risk knowing the embarrassment he would have received or even getting arrested for it.
Well well, the gambling world is a wild place, specially when it's done physically, man can never or will be very wrong to under-estimate what another man can do, people we place high value on sometimes disappoint us even while looking straight into our eyes.
The same way the dude risked losing his money which he did lost, so also after oweing, he also took the risk of running away without paying, and luckily for him, he succeeded, some persons usually don't care or think too much about repercussions, or after-math effect of their actions, they simply just get up and do what they think they have to do, and that's it.
If you happen to be the manager of that gambling shop what will be your action towards the foolishness of such an employee. Will it just be an angry shout or beyond that?
What has happened has happened, shouting won't bring the dude back, if it's the first time such incident is happening, simply advice the co-worker to be more conscious of customers and careful next time.
But if such thing have happened before and it involves the same co-worker, then deduct the lost money from his or her salary as a way to teach him or her to really be more conscious and careful of such customers.
Do you think there is any measure through which the strange guy could be identified since there was no CCTV cameras stationed in and outside the shop environs?
I am not a magician, and do not work in a casino or betting shop, so I believe this question is not for me, so I don't have to answer it since I have none.
