I got banned from buying bettas at Petsmart after I managed to kill five of them in a row. Turns out there was something in the tap water that the dechlorinator wasn't getting. I adopted a dog instead. She's still with me.I got asked not to come back to a little convenience store when I was in college. I kept getting incredibly lucky and winning free sodas when Pepsi used to have those contests where you'd check under the bottle cap to see if you'd win anything. I won about 15 free sodas in a row before they told me I couldn't come back.
