I remember asking for a JD & Coke in a hotel in Abu Dhabi and the barman giving me a lecture - saying it was Ramadan and for most of the year they respect visitors and serve alcohol to them, even though they don't drink, and for a short period of the year it would be nice if we could respect them by abstaining during their religious holiday. He then walked off, leaving me sitting there at the bar alone.
I felt stunned and awful. He returned some time later with a tea tray - cup, saucer, teapot, the lot. I took this as his way of letting me know what was acceptable to drink during this Holy time.
The teapot, believe it or not, was full - of Jack Daniels and Coke. I happily sipped it from my china cup!
