Disgusted in service at Sir Loin Barman and waitresses!!!

Had a family dinner 2 months ago at this restaurant, waited 20 min before someone attended to us, which was the manager on duty. She called over the waitress responsible/allocated for our table. She was very rude to the waitress in front of us, i felt very sorry and uncomfortable for this waitress, as the paying customer i feel this was uncalled for and unprofessional.

The second visit to this restaurant was about 2 weekends ago, 22.02.2020. We wanted to watch the rugby and have something to eat. We sat in the bar area. Upon arrival, i started noticing that the barman and few waitresses kept taking smoke breaks at the bar where we were sitting, laughing and making jokes, throwing each other with sweets and drinking coffee or cool drinks but our table is waiting on a coffee. Service was slow. received incorrect food, waitress wasn't very helpful or apologetic about the mistake, we had to keep asking where is our waitress whenever we wanted to order a drink. when the rugby started the barman put on music on full blast. we asked if we could have the sound of the tv put on cause we wish to watch the rugby and hear commentator speak. Eventually after few times of slow service, wrong food and attitude from barman, we spoke to the manager, who was also taking smoke breaks on regular basis and having coffee with his staff at bar. Later the day the barman started pointing finger at our table and then the rest of the staff would look around and make comments and stare and laugh. this continued for several hours while we were there. the barman also made comments to the table close to us regarding the music situation and i called him closer and asked him why are they acting this way, we are paying clients and did not come to this restaurant to be treated this way and feel unwelcome. His response to us was that if we wanna make a scene we will not be welcome and will need to leave. i was shocked. the only people in this whole situation that was unprofessional and rude, was the staff in that smoking area and behind the bar. A gentleman sitting behind us also mentioned later that night that he also requested sound for rugby game, and they ignored him. we requested the owners details and left our details with the manager and we got no call of email from anyone. the manager gave us a very cold shoulder when we left. i will never visit this restaurant again or have anything positive to say about the restaurant nor refer anyone to go there for a meal. I really hope the owner hears about this and would address this matter with urgency and be understanding. this is the first time ever that i felt so unwelcome and belittled by waitresses and barman. i am much older than 19 years of age and feel there should be respect from all ages.
