Worst service for too long!

We've been going to Ocean Basket Worcester at Mountain Mill Mall for the past 4 years. We love the menu, but reached a point where the service is just totally and utterly unacceptable!! At the moment we are the Only customers. Waited 25mins for service. After receiving our drinks order, we had to wave like crazy ***eons through the window to get a waitress'attention. The reaction: the waitress would much rather chat to her fellow waitresses than receive our order. We saw some oysters on our way in, while on ordering we were told they have none. After enquiring about the ones we saw, she said they're "off"...! The waitresses are doing YOU a favor! And once she even had the odacity to complain about the tip!!!!!!!! That was after I had to actually CALL the restaurant on my phone for service at our table. We took clients to this restaurant and at 8pm the manager told the staff to start stacking the chairs around us on the tables... After enquiring and complaining the waitress told us that they actually would like to go home. Management......? Poor, nonexistent and need to be replaced. Waitresses...... Need proper training and serious manners. Bad, bad, bad service and management!
