Not sure if it was discrimination or racism but it is somewhat related. I was in Morocco 2 months ago and the waiter took my friend's order just fine but didn't want to take mine. It was the month of Muslim fasting and told my friend I should follow Muslim faith just like anybody in Morocco. The waiter thought I was Moroccan. I don't blame him, being Mexican and that day I didn't shave, I could blend in as one of them. My friend translated what he said and holded herself from laughing so I told the waiter "No no no, yo soy Mexicano, en serio. No se preocupe" (No no no, I am Mexican, really. Don't worry). I knew he wouldn't understand me but I wanted to make it clear that I AM MEXICAN and not Moroccan. The guy apologized and took my order.

A few days later, this girl and I were just playing around as we walked near a plaza. We were just being flirty and playful and then police came up to us and asked her if everything was fine and then the guy started speaking arabic to me. Once again, I replied in Spanish (not in English, somehow, I feel english-speaking nationalities are not seen positively in muslim countries) and the guy apologized and told me he thought I was harrassing a poor turist (my friend) and just wanted to protect tourism. No problem.

Interesting how people think I am one of them when I visit Egypt or Morocco. I don't blame them. If I saw them in Mexico, I would think they were Mexican.
