I am not sure what you are objecting to. The documentation you list is standard. What did you expect? Yes, it took you hours to organize all of this documentation, but it was a one time deal. In three months, you will only need to add 3 cycles of credit card statements - the 1040 etc. will not change. And that you now have your affairs in order is a good thing rather than a bad thing. Why you took the trip to the copy center and not sent pdf attachments is also unclear. If you are worried about confidentiality, you can put a "lock" on the pdf files and send the key to the recipient via a text message.

All of those problems seem entirely solvable, and your judging Mr S seems a little odd. Yes, calling you a sweetie was condescending, but it was not abusive.
