Bad Hygiene, Possible ****** and Cold Food

I couldn't fit this in my previous report, because it only gave me a limited amount of words to say and I had to wait 5 days to report again, so am gonna say this here. I went to my Diners, I asked the waiter for sauce, he brought me a sauce that was in a bowl, it was half eaten by another customer. So I then left the restaurant that time, because the previous customer could have dipped his fingers and food in to that sauce. So that was really filthy, another thing is I think that they are possibly ******, they serve muslims before any other customers, I once went there and I waited 15 minutes before a waiter came to me, other muslim customers came after me and got served before me. Also my Food always comes cold, Which I hate, I always have to send it back for re heating.
