Should I feel insulted? (A professional matter)

I am a sales person by profession. Some 20 days back, it happened so that after a long delay from our existing customer in signing the contract I wrote e-mail directly to their MD bringing the matter into his notice. This was taken as an offence by the IT Manager & COO already involved in the process from customer’s end.

When I told my boss, he also said that I should not have done this thing as their MD might fire at them. Also, in interest of customer relations it’s not a good thing. He said that we have brought ourself at the verge of breaking relationship with customer. “At this point I realized my mistake”. There is a protocol of soing everything. My Boss suggested that I should meet individually with IT Manager & COO to cool the things down and apologize and then move forward with the contract.

I did the same. Immediately I went to meet the IT Manager & COO and actually happened to meet with both of them. Meeting with IT Manager was fine but the meeting with COO was a bitter experience.

The COO made me wait outside his cabin. Inspite of calling me into the cabin instead he came outside the cabin and shouted at me infront of his whole staff. I said Sorry to him but he was furious. He didn’t said any offensive word to me. Every thing he shouted on was related to the incident and contract but his tone was very rude and the pitch was very high. He made me sit intentionally outside his cabin and shouted at me infront of 50+ people. After 5 minutes and after my saying Sorry 2-3 times he agreed to continue with relationship and sign the contract. I then turned back and left the hall.

Since after incident I am feeling little upset and depressed . It has happened in my career for the first time. My question is “Should I feel insulted since the COO shouted at me infront of 50+ people?” or simply take it as a part of the professional life. He didn’t said anything personal to me. I am raising this issue only because he shouted at me infront of so many people. I have the concern in my mind “what may be the other people would be thinking about me?” “What about my image?” etc etc…Though the fact is that ‘not even single person apart from COO and his secretary knew me over there. Had it been a closed room, I would not have any concerns.

How should I take it…”Seriously, offensive and insulted manner’ or ‘professionaly, normal & non-insulting manner’. Should I feel insulted or not?
