I was being just a bit sarcastic with the missing payment comment.
On the other hand, at the time of the event, my boss had taken on a legit partner - another licensed pharmacist. The new guy was less ballsy than my boss. Even a single missed payment could have been enough for the car wash guys to want to send a message to the new guy. You don't shoot a guy for missing a payment unless you know there's a backup source for the cash. My boss could be a real prick sometimes. Perhaps they decided to eliminate the PITA knowing that there was a wimp still available to make the payments.
