Forgot to ask for a straw

Hello everyone, A novice dasher here.

I completed a Wendy’s order as the last one of the day, and it included a large soda cup, among other items. Unfortunately, the worker didn’t provide me with a straw, and I wasn’t paying enough attention to remind them about it. I only realized this halfway through the delivery. Despite this, I still dropped off the order, but I feel guilty about it..

In such situations, what would you do? And what are yoir best practises?
