I started work here about three weeks ago and me and my family decided to come here for lunch. I paid one order for me and three other family members with my discount. Then after that I did another with my younger nephew, I didn’t know how to remove the discount so it paid for him as well. Now I’m worried that I’m going to get in trouble for it, will I actually get in trouble? What should I do as I’d hate for this to bite me in the ass.
