I just posted in the other thread about inflight service https://www.flyertalk.com/forum/32350077-post254.html
Regarding your question about masks, the GA made the announcement about the mask requirement and to notify them if they do not have a mask. The wording was something like "If you do not have a mask, please inform us and we will arrange to have someone get you a mask". It sounded like they did not have masks just sitting around and they'd have to call someone. I did not see anyone that needed to get one. On my outgoing flight (prior to the requirement), I noticed the FA offering masks. They were loose in a plastic bag and the employee was wearing gloves. On my return flight (yesterday), upon landing, the FA made an announcement that some airports require masks now and that they will not have masks for you but you can use a garment to cover your face. Strange announcement since everyone on the plane should already have a mask. They also still have the announcement about holding a tissue in front of your face or using your arm if you have to cough or sneeze.

As I noted in the other thread, about half the people removed their mask during flight. I noticed many people in the airport without masks. Nearly all pilots I've seen do not have masks on.
