bad attitude from waitress and manager

we git a communication from this restaurant regarding their rub promotion on thursdays. anxious to try it, we drove from olivedale to revonia. when we get there after giving us a few minutes, the waitor comes and we ask her for the rib special. she then informs us that she believes the special is finished but will double check. she came back shortly after and told us that 2 are available but we must order fast as another couple just came in. so I tell her to put in one order of ribs plus drinks as my partner did not want ribs. he then spends. few minutes screaming about how we aren't allowed to share and how my partner has to also order something right then and there. we repeatedly told her that we understand that and Will not share but he just needed a minute to go through the menu, but she can place the other order in the mean time. she then started screaming again about how "people" do this and end up not ordering anything but sharing the food we repeatedly told her we understood the rules. after about 10 minutes of this back and forth, she agrees to place the order. but only for the manager to come back to our table telling us the ribs are finished and that the last 2 were taken! he said we are free to buy the ribs at the normal price. I don't know whether its racial profiling or just plain bad service, but the way we were treated was completely unacceptable. all that drama for ribs! ps. the people who came after us, got the ribs!
