The Perfect Job Has ALIENS!!!!

So, I really thought that this was FINALLY the perfect job:
-extremely flexible hours
-bosses who are believers and nice as frickin banana bread
-I can lay down on the job cause we sell massage beds
-when I'm not laying down on the job I'm chatting it up with regulars or reading
-did I mention soothing music and virtual silence for 4 hours?!
What's the problem you may ask? My boss is taking a much deserved vacation this week and I'm working with a couple of volunteers to keep the place running. Today a chiropractor was my volunteer helper which was great! She was nice and was doing free spinal assessments for people who came in...what threw my day into the paranormal (literally) was her "friend" J who came to help out too. J was 50 BILLION chips short of a fiesta platter!!!
She walked in yawning so I made some comment about her needing some coffee. Her response was, "Oh, that yawn is just the aliens trying to communicate with me." I did a "heh, heh," chuckle and then paused. Is this lady being serious?!!! YOU BET YOUR SWEET PATOOTIE SHE WAS!
She proceeded to tell me that the aliens had given her the ability to communicate their will for us through her. She could tell by twirling her necklace what your "job" was that the aliens needed you to do. According to her I was carrying out my "job." AH! For the next 4 hours she communicated her views to nearly every frickin customer who came through the door!!
J would stand over someone as they lay down, find out some little twinge they were feeling and proceed to noisily breath her alien/demonic voodoo all over their body. She sounded like she was trying to breath through a contraction! I couldn't concentrate cause their was obviously SOMETHING talking to J that had invaded my serene, God blessed work place!
See, mediocre religion I can take, but demonic presence is another story.
Interestingly enough, the customers who came in were not the normal people I would see on a daily basis; it's as though Satan was able to pull them in because of J's presence. Blah! Of course as soon as J and the chiropractor left, order restored and I could effectively encourage the customers again.
I am so frickin pissed that Satan dared to disturb my sanctuary, but what should I expect...Satan hates it when good things are happening anywhere.
Here's were I need your advice, dear reader, what should I do about this? I'm going to ask my boss(es) when they get back whether they sanction J's presence here as someone representing them. If so, do I quit? Or do I simply request to not work whenever J is in "volunteering"?Maybe I was brought here to counteract J's presence...maybe not. I welcome your comments. Just goes to show you there's no perfect job.
