Yes, so embarrassing!
I took him into our local flower/home/garden place and within 5 mins of being in there, he squatted on the floor and pooped. Ugh so embarrasing... of course I picked it up and threw it away but I still felt like people were watching.
He has done it once in a pet store also but that's not as embarrassing to me, since it IS a pet store... haha
Oh yes and he very much enjoys to poo on the cement around my dads pool.
oh well at least it makes it easy to clean up...
