When I worked for Nortel Networks in the late 90’s, I had a muslim manager who decided to take us out for team building. He booked dinner at the Cheesecake Factory at 7PM during Ramadan since he could not eat during daylight hours. I didn’t go.
I dond’t really understand fasting for half a day. I’d be more impressed if they did it for , oh, 40 days straight, including nights.
