This reminds me of a Muslim librarian that checked out my books for me once. He was those dress and beard guys and I had a hijab, and I felt him looking at the titles of my books...Last book he picks up to scan, it was an RL Stine book, he goes "tsk, why read this stuff sister?"
That happened to me when I was buying The Satanic Verses and I'd always get weird looks when I was reading it on the train.
Or when, I'm outside without my hijab, I'm drinking alcohol and I got carded - I look like a kid - and the guy sees my name and he's asking " Aren't you muslim? I thought you guys aren't allowed to drink. " And it's just a turn off when I was just supposed to have some fun with my friends.
I feel your pain
It's funny when muslims who sell alcohol try to preach to me when they read my last name. WHY ARE YOU SELLING ALCOHOL IN YOUR SHOP IF YOU'RE SO DAMN PIOUS, YOU MISCREANT? And my last name couldn't be any more ironic, it means 'Beloved of Allah' XD
