I had a lady come over while I was playing and starting to attack me physically screaming STOP THE MUSIC!!!!!!!! I kept playing with one hand and stiff armed her with the other until security dragged her off me...... different levels of NH's aren't all the same ...... depends on the department your playing for EG: Ind living, Assisted living, Health care, Alzheimer Reminiscence, Drug Rehab, etc,....all different audiences and situations for the entertainers to experience. But, a well trained attentive Prof staff can ease any disturbances if occurred.. only 50% of my jobs are in these facilities, and it's rare for any trouble while performing.... most of the time its a very gratifying gig!
