One Hostess working in Business Class (Dolly maybe) was exceptional. Helped me figure out how to release. The video screen from its stowed position (sat just behind Business Class). Felt all around to find a release button, even had my hand on the release button. dolly came back to help. At first neither her or I could find the button to release the stowed screen. Later I came back from the restroom and there it was, up and ready to use. Maybe paint a red arrow for some us dum ex pilots. Felt a bit stupid but Dolly came to my rescue Ron
