Bad Service from a waitres

We stood at the door waited to be sat down as the norm in any restaurant. The waitress came our way and showed us to a table without a word, we proceeded and sat down. The same girl who showed us the table showed up and threw the menus on the table and walked away. To my surprise she disappeared for about 5 minutes. while we sat there looking around for help. My husband spotted her chatting away with other waiters at the deli. One of them noticed us and asked her pointing at us, she shrugged her shoulders walking away saying I don't serve cheap skates. Boiling with anger when one of the waitresses came running to the rescue and apologized noticing that we overheard this conversation. I refused to place my order and asked to see the manager. Who also apologized and said he would sort this out. " Barbra the waitress" came back to apologies in her apology she said we were too busy talking she avoided greeting or introducing herself to avoid disturbing. I fail to understand why throw the menus on the table why refuse to serve cheap skates when you haven't even heard what they have to offer. Yes I got a call back offering me a free meal but is that going to fix unruly waitresses. Is there a specific appearance one needs to have in order to be respected in a restaurant. I refuse to be disrespected like this ever. Ocean Basket sells good food and should hire people who understand good customer service. Barbra is very rude and arrogant and should rather be based in the kitchen where she does not see customers.
