Terrible waiter (thai thin man)

Me and my friend decided to try thai food after mass, we drove all the way to Edmonton from Leduc and took us 34mins to be exact to get there, we were very excited that we are able to locate the place. When we entered the restaurant, we were greeted by a lady hostess and a server and asked if we had a reservation, luckily, we were still accepted even though we didnt have. we started to like the place until our "SERVER" came, he was thai thin man, he was rude and very unfriendly, we had placed our order and after 15 mins, 2 items from what we ordered arrived except the other 2 items so we asked if its on the way, the "WAITER" answered rudely saying that "Its coming, just wait!". we kept quiet and beginning to feel annoyed by his behaviour. finally, the 2 items came, after we ate we immediately asked for our bill and decided not to give tip as we were not very happy at all. While we were walking out the door..guess what??? the server " Thin Thai Man" came after us, and had said "NEXT TIME, IF YOU DONT GIVE TIP, BETTER ORDER TAKE AWAY!" un imaginably rude...we will never be back to this restaurant anymore and for sure will tell our friends about this terrible attitude. NOT RECOMMENDABLE! I will have to speak to the manager or the owner. This Staff needs to be trained with customer service. He is not suitable of it. He should be working at the back office not related to any customer service job. EXTREMELY DISAPPOINTED
