Sushi was okay, not bad but just okay. The service...

Sushi was okay, not bad but just okay. The service was very poor though. Our waiter was not attentive at all. He didn't refill drinks, he did not bring napkins back, and whenever we called him over he would ignore us. Several times he made eye contact with our table but refused to come over. It wasn't a very busy time period when we dined either. We were the only table in his section at the time. After we finished, we were probably waiting 20 minutes for our bill to come. After we paid, we ended up leaving to which he comes storming up asking about why we tipped him poorly.

Now, I am a firm believer in tipping 15%-20% but based on his inability to check in with his table, the tip he received was a reflection his poor performance as a server. On top of that, what kind of restaurant allows their staff to chase customers out?

Luckily, the manager was willing to discuss the issue at hand but I seriously hope that never happens to any future customers. Completely unprofessional.
