Abyssinia Restaurant

My first time being to this restaurant although I have been experienced in Ethiopian food many times before and my family is also from there , when I first sat down, I wanted a beef sambusa but was guided to chicken wings instead and I did feel a bit offended as a black woman, it seemed as though the server (who I assume is her daughter) just assumed maybe I didn’t know anything about their food but I still thought it was a little rude but kept dining in. Everything in terms of food was delicious, I had to ask for my sambusa again and a spoon and fork which I felt should be on the table anyway because not everyone will eat the whole thing with their hands but for the most part I understood and enjoyed the experience I didn’t like how it wasn’t mentioned gratuity was included within the check so my meal was a lot more than what I had planned for but thankfully I had enough. I asked her about it (the younger one, assuming she’s the other woman I mentioned daughter) and she couldn’t even explain to me what gratuity was. I’m not trying to be offensive but I just feel if that is the policy it should be stated because otherwise it’ll leave you feeling scammed. I did feel a little taken advantage of given they possibly never seen me around but again if it has always been that they include gratuity, I have no issues, I just wish it was mentioned
