You obviously do not understand Islamophobia.
It is Islamophobic when Muslim women wearing hijab are being attacked all over India whether there is a ban or not is irrelevant. Even the poor families of hijab wearing women are not spared.
Zoya Ahmed* alleged that her 20-year-old brother Saif was assaulted by a mob due to her decision to protest the ban on Islamic headscarves at educational institutions.
Like I said, culture flows from the top.
Whether the manager is British or British-Indian or Indian-Indian does not matter because it is the work environment that allows Islamophobia to fester. Ask yourself, where did the manager get the idea to treat Muslim women in such a way? You can be sure the owner and colleagues felt this was appropriate behaviour. They obviously regret it now that they have been caught.
