I'm so sorry! What an ignorant oaf the renter is, not even thinking/knowing/caring the pee will damage the plants. I am glad you found out so you and AJ can keep a watch on this guy and pee on him and his if it doesn't stop. I think I'd make AJ insist on a formal apology from the guy (if he wants to stay?). Or, offer him some unwashed cucumber slices in a salad after you pee on them :-)

When my brother was in high school, we use to take "leftovers" to school for our lunches and they were usually quite good; meatloaf sandwiches or even steak. My brother didn't lock his locker (this was Southern California in the mid-60's) and someone kept stealing his good luches! So, my stepmother and he "made" a lunch that consisted of a dog food sandwich (made to look like meatloaf) and replaced the cream cookie filling with a horseradish filling, that sort of thing but put a nice apple in to help make the lunch look believable. It was stolen but never again
