Sonic Drive-In review: Receipts withheld & employee survey fraud

As I wrote in my last survey, sometimes employees do not give out receipts with completed orders. Last time I insisted on receiving my receipt, I saw it was one with a survey ID on the bottom. I recently used my code for the free route 44, only to be handed another receipt. I told the employee that this was not mine, but she assured me that it was the practice at that location to give the survey receipts to their "Regulars." I came on 2-25-2020 at 1:20PM. The receipt I was given was dated 2-19-2020 2:57PM. The employees at this location are causing deliberate fraud by withholding receipts from some customers and giving them to people that did not purchase said items. My guess as to why this is happening, is that the "Regulars" are giving high praise surveys in favor of these fraudulent employees.
