I suspect he's a child who is not willing to lose money but want to get money from gambling
just look at next month he must come again here to bring other problems
I guess that not just a child who does that but some adult people can do that because they do not want to see their losses so they will complain to the casino about their losses. If they can realize the consequence of playing gambling by losing their money, they should accept that and not complain about everything they will get from gambling.
Most of them think that gambling will give them easy profits, so that kind of mindset makes them drift into winning even though they haven't started yet. So, gambling anywhere, of course, must have the same mindset to be able to accept losses and be ready to accept these risks, although we also have to have strategies and ways to play which may have to be different according to time and conditions. Here at Stake.com, you can gamble according to what you are interested in because there is not only one type of gambling available here, there are several types of gambling such as sports and casinos that have many types of games of course.
