Thanks, Phil.
I perform at nursing homes and retirement villages, hand out 80-page soft-bound books that I've self published, and take them back at the end of the singalog. I feel safe doing this.
The problem comes when a resident begs to buy a book. I refuse to sell them and occasionally give the book to the resident. Since I'm being paid to perform, I'm not comfortable taking money from the audience. Especially at the less well-financed institutions. However at some places that are quite upscale, I know I might be comfortable selling books, with the permission of the facility, of course.
Hope this additional information helps.
