It is probably not a record, but it left an impression with me:

A girl who started the day I did, came in on her second day right before the branch opened and turned in a written resignation to the BM. She said goodbye to me and left. Immediately, both BM and AM starting saying shit about her like "she couldnt hack it" "what a loser" etc etc etc. That is the very instant I realized how evil this place is and how evil it makes people become.
