I wouldn't dismiss his observations initially. It's his AR and both you and him can be true. Perhaps his visit occured after your 4 or 5 visits, I'm speculating here. However, If as described in his report is substantiated then it's a good PSA for the next punter to proceed with caution and perhaps verify if they notice the same thing? Any report of physical health symptoms should put the rest of us on high alert. Esp those with partners and/or in committed relationships.
