对牛谈情

Bad day today...went to UOB to explain some findings to their IT department with regards to some issues encountered last thursday which requires the activation of almost the whole team...There are 3 ppl represented by their IT department. I explained once...2 get it but the "head" somehow keep rejecting the explanation to go into his head...duh...really 对牛谈情...A findings meeting became a heated argument between him and us. Really stupid a*****e to work with...Anyway he is getting to everyone's nerves, even his ppl also the same. Sianz...
