Which is a reason that I'm happy to accept if I'm in a country with a majority religion or a local culture that I have to respect. But how many followers of Islam are there in the country? By Google's reckoning together with Wikipedia, Christianity leads with almost 80% adoption in this country. Islam in 2007 was at less than 1.5% (most recent stats I could find in the last 15 minutes). I can understand making accommodations for people whose religions are different to yours, but I can't get behind changing or dropping something from the menu, or a supplier or a service provider entirely because a Halal certification was so important to a relatively small portion of the population (thus, a small portion of the profits and revenue the business would bring in as a result).
There are good aspects to the certification that I can agree with, however, like stricter hygiene standards and tighter procedures. But overall, it just doesn't make sense to me. If the business case is there and it's beneficial to the business' bottom line, then okay, by all means.
