My friend and I went to a theme park. Our car parked outside of the park. To enter the theme park the staff needed to scan our tickets. But once we entered, we realized we didn’t pay for the parking so we need to get back to the parking lot, which is outside of the theme park and we needed to pass through the staff who scanned our tickets and told them that we wanted to check something briefly and will come back soon so they could let us in. I wonder how I should express this.
What I said was:
can we get out for a moment to check for our car?
I guess it sounds awkward but the staff figured out what I meant. But I was wondering what some of the more natural and accurate ways of express this are.
