LBC Express review: your employee in turbina calamba branch is very rude and unethical

Happened around 3:25pm. I didn't got the name of the said employee because i'm in a hurry and almost lose my temper when he treated me that way. I'm waiting for my name to be called, when it's my turn he saw my indicated amount in the encashment form amounting 27000, he reacted "ay puta! Wala kaming malaking pera" sa mall kau pumunta pag gantong malaking pera", saying it without any"po"and sounds like irritated. So I replied"but i've been here before when I claimed big amount". He said"wala nga 16000 lng meron". So I left with heavy hurt and thinking what's the best thing to do to teach him a lesson
