I’ve just had the worst restaurant experience in my entire life!

I have been to Alisan three times before and the food and service was fine. This time my husband, my 2.5 year old and I didn’t even get a chance to order the food. A waiter came to take our order. I asked what ‘Young Chow’ rice was. ‘Mixed meat’, he said rather abruptly and got very annoyed when I asked which meats exactly. Turns out there was seafood too which my husband is allergic to! He finally took our order and I asked for jasmine tea to drink. My husband was about to ask for his drink but the guys grabbed the menus and rushed off. When I said ‘Excuse me, could you please get my husband a drink’, he got very annoyed and told me that he would come back for that. Seeing the shock in my facial expression, he came back, slammed the menus back on the table and asked looking at me ‘Yes, what do you want to drink then?’, like he was doing us the biggest favour ever! At this point, my husband said he wanted to leave. I asked whether I could speak to someone else but the waiter kept smiling and saying ‘Sorry, you feel this way’. He didn’t look sorry at all and wouldn’t call anyone else. I then said we were ready to go and the guy started moving the high chair with my daughter in it! Totally bizarre! I went to the counter at the entrance and asked to speak to the manager. The gentleman there said ‘No, he is the manager’ (smiling) and then both of them escorted us out!!! Oh my God! I am still in shock. I feel utterly humiliated. There is something definitely wrong with this guy as there is no possible explanation or justification for his behaviour. Their chef might be good but the attitude and conduct of their front staff is disgraceful.
They don't deserve their customers
