Many people who are coming from UAE say that here in Qatar people have much better behavior than those in UAE.
Also in Emirates the taxis complains about some UAE people.
You must also know that there are some UAE people who are much better than here in Qatar, and vice versa.
It is only the percent of people, now in Dubai the population exceeds probably 1.5 milion and as the population increase the probability of more problems such as abuse increase in most cases.
The abuse happens because people do not realize that there is God who is watching them and they do not reallize that their actions are counted.
Abuse can happen in many ways, I think not giving the salary is one form, in our religion we are asked to give the worker his money before his swet dry, this is to show the importance of being fair and responsible for others.
Always remember if you do something bad and unfair you will sure later suffer for not being fair with others.
Always be good from the beginning and the natural person who does not have physcology or mantality problem will always like people to treat him very good, therefore the natural person will treat the people the way he want to be treated.
