Personally, I had bad experience Trusting my so called "Colleagues" too much when doing businesses together. It really leaves me devastated and sometimes wonder about what I have done wrong to deserve treatment like cheat, supplying sub standard goods below order specification, and stealing my business ideas.
What experience do you have Trusting colleagues when doing business together?
There is nothing wrong with trusting people when doing business, but what is necessary is understanding the need to always go through details of the business. Even when you are told the price of a product or service, always ensure that you crosscheck to avoid being cheated at the end of the day.
