goodbye to koa house. aloha has many different meanings in hawaiian. for my post, aloha means goodbye. usually i like the koa house. theserviceisn't the greatest, but the food is good and it's one of those places that has been in kaneohe awhile so i like to go there and eat. this morning we went to eat and while we were waiting for the rest of our party to arrive, we ordered oatmeal for the kiddies. the waitress acted like we were bothering her because we wanted to order oatmeal now and wait for the rest of our party to order our food. she was not very helpful the entire meal and even forgot someone's toast and hot chocolate. we didn't make a big deal of it and just figured she's kind of rude. our bill was paid at the front register and the tip was included. she wasn't the best, but we left a 10% tip. as we were loading up in our cars, our waitress runs outside of the restaurant and yells at us with a ton of attitude, "excuse me, excuse me, you guys didn't leave a tip. this is a restaurant you know." then she went inside. i was shocked. she did not just yell at us for not leaving a tip when we did. i was so upset, i went back into the restaurant and asked the owner if we paid a tip. she said yes and i looked at the waitress and instead of just saying sorry, she yelled back at me and said well she (the owner) didn't tell me you guys left a tip with her and she walked away. again, what?!?!?! and everyone in the restaurant is hearing this because it's not a big place. i told the owner that she better talk to her employee because if that's the way you treat your customers, we are never coming back. after we left, we said we should've just taken our tip back. we were so mad that we went back to the restaurant and the owner kept saying sorry, but then she said well most people pay at least 15% tip. again what?!?!?! we told her that tip is not mandatory and based on service. and 10% for a big party is a lot of money to begin with. am i wrong about this concept?? needless to say it was a terrible experience and i'm not going back there to eat!!!!! i'm sorry to say the waitress was a hawaiian local lady and the worst thing was, we were with visitors from the mainland and this is what they saw of our local restaurant. i'm so upset,
