@gnusocialjp mixed word choices, informal and formal words, wrongly use words in context in business presentations, not just a communication between colleagues. I can't give an example but I'd know if people do in my native.

Even I agree about result is the most important, but some people I know can't get rid the first impression easily. It's getting worse if present a suggestion, they would hardly trust it. But this case only if we speak same native, I've never been in formal situation with different natives.
