I have been known to bend a few rules from time to time.
"No, I wasnt handing out biscuits. I was handing out canine nutritional supplements. You said it was biscuits that werent allowed, I thought you meant the kind that people eat with gravy."
I have mixed feelings on giving out treats after I had a customer ask me "you didn't just give my dog a treat did you? He's on a strict diet and gets violently ill if he eats anything outside his diet." Oooopps
