I agree that respecting the rules of the country you are visiting is important, but I also believe that certain changes should be made to accommodate the visitors during the world cup events.
It's good to know that the Qatar world cup was peaceful and there were no issues related to alcohol consumption. Maybe other countries can learn from Qatar's rules and implement similar ones to control alcohol consumption and prevent any issues during the events.
Everyone should admit that fact that Qatar was phenomenal and how things went smooth because of no alcohol policy and they should learn from them and take it as an example that to organize a smooth peaceful event where different countries cultures and religion have to come face to face for month or two how things can be arranged in a good way.
Even the alcohol policy is been given relaxation to give the best experience to the international audience visiting the country. Separate place were allocated for them and certain time limits were also mentioned. This is really good and helps avoid unwanted issues arising between. In most people's case, alcohol is being consumed as medicine that helps them to be more expressive. Allowing with limits is always needed.
