Did I do the right thing?

First time getting an Arby’s order and I go in and the place is a mess as far as staff goes they have nothing in order so it took about 10 minutes to get my order. As I get the order there is my first ever double batch I guess it’s called and I accept it. I’m then waiting 5 more minutes after already confirming the first order. I hit the remove the second order or whatever the option was. There should have been little to no wait right? Why would I get a second order or a stack and have to sit there waiting with the first persons food. Doesn’t seem fair to the first person. I was worried that if I waited for 10-15 minutes it would ruin the entire current dash or something. By the way it’s my third day and got a batch order at the worst possible time lol. That Arby’s was horrific
