If I had to guess, it might be that the indexing where you push a new serve event from a self-checkout is off by 1. If all else fails, you could perhaps trace your code since test case 8_4 is a public test case! Sorry if this wasn't of much help.

It seems like it is not waiting at all. Maybe theres an issue with customers waiting in the queue for self checkouts? Maybe you could provide us more detail on how the self checkout class is implemented.

maybe there is some issue when you try to update the queue

I think it could be a bug when a waiting customer needs to be served by the self-check that it isn't waiting at since everything before that seems to work. It might be a problem with the way you pass the wait into a serve event since it seems as if 15 just waits forever without being served.

I had a similar issue to this as well, you might want to check to see how you're assigning the servers within the self-checkout itself. It might be the case that it goes to wait, but someone else arrives to take the counter so the event isnt processed anymore. Depends on the implementation of the wait event and how servers / events are updated

thanks all for the suggestions, apparently it was a problem with some conditional statements regarding the management of the queue and also me double counting the wait times from self checkout servers... solved!
