Narrative: During aircraft cleaning; the aft galley was being catered. They catered the front next. Upon completing catering; and when the R1 door was closed; I noticed that the warning strap was across the window. I immediately called it out and said 'why is that strap across the window'? The door was obviously disarmed as there was no slide deployment. D Flight Attendant was with me. The CSA (Customer Service Associate); who was waiting at the R1 door; then said 'you gave the caters a thumbs up when they knocked and the strapped was attached' which I do not recall doing. D Flight Attendant didn't see the warning strap in the armed position when she boarded the plane either. I immediately moved the warning strap to the disarmed position and noticed that the velcro strap on the extension piece was worn out to the point where the extension would not stay attached. It constantly fell down and hung.I told the First Officer as she was leaving the flight deck that we had an issue with the R1 warning strap. She indicated that they were about to time out and discounted my comment. I made her look at the strap. She came to the door and said 'no; it works; see'. I showed her that 4/5 attempts to place the strap on the Velcro didn't work; it would fall down. She said 'well you gotta talk to the Captain about it' and then entered the bathroom. I then proceeded to talk to the Captain. He stopped me before I even started and said 'if you tell me anything I am obligated to put it in the book; so is this really important?' I said yes; I have an issue with the warning strap. He also indicated that they had a timing issue and couldn't take any delays. I told them that I needed Maintenance. Maintenance came and fixed the strap. I don't know what happened with the strap being across the window in the armed position. I can only speculate that catering attached it while it was hanging down. If it was in place; they shouldn't have opened the door; the CSA should have also said something as she was waiting by L1; apparently watching; and the entire inbound crew should have checked upon deplaning. I find it odd that all of these checks would have been missed. Furthermore; I didn't appreciate being put in a position where I had to make the call if we were going to take a potential delay and possibly cancel the flight due to a timing out issue. My only job is to bring cabin discrepancies to the captain's attention. This was a poor example of CRM. This morning; I had a conversation with the Captain regarding the events yesterday and reiterated what I have written in this [report]; about poor CRM and putting me in an uncomfortable situation. He agreed and said they handled the situation poorly. As we are flying together today on an ETOPS flight to ZZZ; I didn't want to there be any communication issue before we left. Our conversation was pleasant and we cleared the air.




Synopsis: Flight attendant reported a CRM issue developed with the flight deck crew after reporting there was a minor maintenance issue with an aircraft door.
