7-Eleven review: Egg salad sandwich - expired

I went to the 7/11 near my work to get an egg salad sandwich for breakfast this morning (12/13/21). The clerk was in such a hurry to get me out the door, I did not get a receipt. The sandwich expired yesterday (12/12/21).
I would like a refund for my sandwich, but I am not even sure how much it was because he did not give me my receipt. The bread is turning a very dark brown around the edges.
