Thanks everyone for your comments and thoughts.
After checking my records, this was the first and only time that a
credit card issued to this person was used in the past 2 years. So I knew I wasn't dealing with a repeat customer, instead someone who needed to blow their truck bed out.
I ended up doing something along the lines of what HeyVern suggested. I stopped by his practice (he's a local doctor) and politely asked to speak with him, when I was told he was "busy", I explained who I was and left pictures from the first post with the receptionist and my phone number. I left. About 10 minutes later I got a call from him apologizing up and down and how he "felt bad" while he was doing it. I did not address him as "Dr", instead I used his first name. I explained that he left the place a mess for the next customer, and there is a difference between using the facility and abusing the facility. He offered to pay a clean up fee, I did not accept that offer.
I was satisfied with this. Knowing that there would be some embarrassment with his office staff. I was also satisfied knowing he'll never be back, and that was my goal.
As for those who simply say "suck it up butttercup". That's cool, and you do you.
