The Ministry of Interior makes sure that the law which was formulated in 1968 is given wide publicity leading to Ramadan. The rule according to law No. 44 of 1968 says that anybody caught eating, drinking or smoking in public during the daytime in Ramadan, along with those who compelled or abetted them to do so, would be given a fine of up to KD 100 and/or a prison sentence of one month.
I have not heard of anyone personally known to me being caught but it is understood that the imprisonment ends on the last day of Ramadan. This law also gives the Ministry the powers to ask certain establishments to close during the fasting hours and Restaurants are not open during the day hours till the break of fast at sunset.
It depends on where you work and it is necessary that you respect the local customs as any unwanted exuberance is considered an insult to the tradition of fasting that is followed by most Kuwaitis.
In some organisations, the pantry is kept open for non - muslim expatriates to take their food, water, etc in seclusion. In most organisations the Kuwaiti colleagues do try to make it clear that they do not object to your taking food and water during office hours if it done in the pantry.
In an organisation I know of non - muslims had not paid heed to the sentiments of the fasting muslims and had gathered at the pantry, as if for a picnic. The action taken was that from the next day the pantry was closed.
I have not witnessed it but it is understood that if a muslim complains about your having taken food or water in public view, during the fasting hours, you can attract the penalty we have discussed above.
School children are allowed to bring their lunch and have it in their classrooms instead of the usual places like the playground or the auditorium. Sick and invalid people are exempted. I understand that even sportsmen are exempted but we do not take the risk and on Fridays when we play cricket we make sure that when we drink water we are not sighted by any muslim.

Ramadan is a holy month and the best time to ask for a raise. I am not sure anyone has actually done it or not. Kuwaitis give away 2.5% of their income as Zakat and try to be the most benevolent during the holy month.
Ramadan is the best time to relax. Office hours begin at 9.30 AM, two hours after the usual start and end at 2.30 PM, half an hour before the usual end. If your Boss is a Kuwaiti, then it is the best time of the year. No pressure & no irritation.
Muslims like to share during Ramadan and there are meals called the 'Ghabka' held at almost all big hotels in the evenings. Large AC tents are put up and a variety of food is spread for dinner. Non- muslims are invited and there is no restriction on the number of friends you take along with you. I am invited to one tomorrow.
The bad things about Ramadan is that traffic is really bad. Not as bad as in Delhi though, but bad by Kuwait standards. The reason is that people have not slept well and need to rush home to get sleep. Therefore some rash driving and some cat napping on the wheel. Ramadan sees a large number of accidents.
