Big Mamas, Coron Palawan - Worse experience ever

We went to this Big mama's restaurant twice with my family. The first day we went there we have to leave because we order mango shake. The server name was RENO, he said he can't serve mango shake due no sugar available in the restaurant. So we left. On the second they we try to go to their place again. He (RENO) was so rude on us the way he ask questions ,what do we want to eat?looking on our face like we were criminals for ordering foods . I ask one of the guy why Reno so rude. The other server said : " ganon talaga yon si Reno."
