Rude colleague

Our team leader implement cross checking system to the team. Every case that we are going to submit needs to be cross checked by another team member first.

Just now, IL brought his case to us and asked if any one of us (MC, LP or me) was free to check his case. As MC and LP were busy with their cases, I volunteered to do it for him. Well...I regretted taking the responsibility. First of all, the terrible handwriting. Secondly, some missing details in the application form. Thirdly, no counter signing on the corrections. Fourthly, his attitude.

I was checking the case like it was my own. I checked the forms and ensured all documents were attached and in place. The next thing was to ensure the accuracy of the calculations and analysis. I went into details by asking him how he derived his figures. He showed me his impatience and talked in a harsh tone. I told him not to talk to me that way while I was putting my heart checking through his case. Apparently, he didn't appreciate that. He thought the case was error-free and just wanted me to roughly go through and acknowledge that I had vetted his case. He said he gonna rush home. Hello...Neither did I have a lot of free time to do this for you!! I gonna cancel my date with bf because of your unwelcome case, F***! So infuriating! I never wanna check his case again...I just can't tolerate people who don't take pride in their work and still being yaya-papaya!
