Really slow service

Me & my fianc? went to the said branch coz my fianc? loves primi we arrived at about 7pm. Seated we were asked what drinks we were gonna have. I ordered a glass of water & my fianc? a glass of wine. We waited 15min for the water & wine then the wine came & not my water. It was 7:30pm already & none came to ask what we wanted to order. I was upset & called the manager. I told him about how slow the service is. I the told him we rather gonna go to one of the other branches where the staff are friendly & swift. Please train your staff to be more fast. Btw when we sat down there was a group of guys that came in after us & they got served quickly they even got the complimentary bread. Thanx
