In this case the "1st customers " are already serviced and the 2nd customers still don't get serviced. I would maybe have a diff price to the 2nd customers so the 1st customers don't b!@#H about it.Say if a field is not full and a "no grade point" racer wants to enter then charge extra to get in the field......1st customer gets the less expensive deal...Just an idea...
