Communicatiom is Vital

I think communication between hosts/waiters are important. Waiter A serves me , its 18h45 and I'm aware that the half price on ****tail ends at 19h00 . I ask the waiter if I could please get the special but have my second ****tail later the evening...he agress and waiter B then bring ****tail one ... moments later waiter B tells me I didnt make it in time and waiter A didnt inform him about anything. He tells me that he will try and find the person who served me....its been 20min and Im still waiting , typing this experience out on my pad ...what turned out to be chilled sunset has now turned into an awkward wait and a customer feeling neglected because no one cares about her simple bill... its been a hectic Monday and because I had been here the Sunday , I thought I could be a potencial regular but this experience has just put a damper on my perspective ....its going on to 30 min and still no one has clarified what I ordered, but then I just a mere customer compared to the other full tables ranking up their bills :) ... thank you Obilivion.
