Burger King review: Refusal to give senior soda price and receipt has no survey code

I went to #633 Burger King in Laurel, MD on 1/26/21 5.55pm order # 322511.
I ordered 2 chicken sandwiches and 2 onion rings and a senior Dr Pepper. The server Kendrell refused to give me senior price for small soda and charged me $1. I could have driven to McDonald on my way to get a large sods for $1.
Also the receipt was torn off without the survey code. I could not do the survey then. If Burger King is not going to give any senior discount then put a big sign or advertise on TV so that the customers can go to other stores who respect the seniors and give discount.
