To take it from someone means to believe them because they have experience with what they are talking about, but this context suggests that the speaker is not experienced and therefore cannot comment
Given the statement "I am not experienced to comment, but, he would have used your professional services more than once if he hadn't been impressed.", is the statement "But take it from me, he wouldn't have used your professional services more than once if he hadn't been impressed." is true?
- Yes
- No
- I don't know
