Shocking service bad attitude

Have been for breakfast on numerous occasions . Last visit was a very bad experience , waited over 30 mins for breakfast after following up 3 times. Ended leaving without any food. Chap at the cashier is very rude and abrasive ,disinterested and lacks customer s****s. On previous occasions have not waited as long ,but still slow, it intrigues me that the service is still substandard, given that every time they have had maximum 6 to 7 tables. Not sure who is managing the place , that is certainly not visible. Such a pity , because it is a great venue and has a super vibe. Coming from the hospitality arena they have no idea what service is all about.
