I’m on the side of Bucees here. Ducks are feces factories and the thought of one strolling through food prep areas ranks right up there with the woman I saw plop her diapered get on the table at a pizza place near Emory and proceed to change a big number 2 filled diaper. I didn’t see anyone saying anything to her so I crossed that restaurant off my list forever. That was in the mid 80s and I never went back.
And I suspect the duck was not a valid service animal. Lots of a$$holes started bringing their “emotional support animals” on airlines a few years ago I was on a flight where some little ankle biter no doubt some a-hole’s “emotional support animal” ran down the isle and pissed on the floor a couple of seats ahead of me (Southwest).
The election of Trump made millions of people lose their minds and turn to any and all coping mechanisms. They have since resolved to never let such an election happen again.
