Due to Islamist pressure, many Subway stores across UK and Ireland are banning porn products and are only carrying meat from animals slaughtered according to Islamic religious precepts (aka "halal").
Subway removes ham and bacon from nearly 200 stores and offers halal meat only after 'strong demand' from Muslims
I think this is bullshit. This is directly restricting choices for non-Muslims just so Muslims are not offended by having to sit next to someone with bacon on their sandwich. Giving them choices they like (although halal slaughtering is very problematic in itself) is one thing, restricting choices of others is quite another.
Out of 1,734 Subway outlets in Ireland and the UK, 200 will only serve halal products while excluding pork. If they did not exclude pork from their menu, it would necessitate special training for their employees to avoid contact between pork products and halal products. Separate utensils, separate counters to prepare the food, separate refrigeration sections etc... That decision to dedicate 200 stores to halal only appears to be based not on "Islamist pressure" rather the customer demand based on demographics per location. It makes sense that Subway would provide a service compatible with the predominant cultural profile directing the consumer demand in each location.
As to objections to the halal slaughtering, Subway communicated that all their halal meat comes from halal slaughtering houses who use stunning prior to slaughter. As to "restricting choices of others", considering that there are still over 1200 Subways serving non halal products, how much "restriction" are you assuming will affect non Muslim consumers in the UK and the Republic of Ireland?
