Back around 2006 I ordered from the patio at sonic, took them a while to answer, I was the only one there, weeknight 8pm'ish. I can see them standing inside talking, finally take order.
Half hour later get food, it's cold, cola instead of the unsweet tea I ordered. Re-ordered 10-15 minutes later get another drink, cola again. Push button again they stand inside looking at me but not answering, I throw drink over handed spattering it on window. They stop looking at me, never did get the unsweet tea.
