First of all, how is it possible for user one to get to the payment page? If the selected ticket is not available anymore it should reflect this on the very next request to the server.

Another option would be to let user one finish the payment as usual but internally set the status to "on request", meaning that it should be assigned a ticket as soon as gets available or an someone must manually try to resolve this by trying to get a ticket for this user some other way and assign that to the user. The worst case would be that this fails and the user will get its money back (and maybe something like 10% off the next purchase). In some countries there are rules on how such should be handled. Something like tickets can have specific rules that are more lenient due to the fact that you system might depend on other systems that do not only sell tickets to you but also a lot of others. The rule could be that it is possible for the selling party to cancel the purchase in for example 24 hours but of course this should be mentioned to the user.

It would be best to show the user a message about being out of tickets on the next round trip to the server. For websites it is hard to show real time on the page without network overhead. I also wouldn't be to worries such pranks because there is really no fun in doing it. The prankster won't see any direct result and therefor won't get instant gratification doing such a thing. We should of course mind about people that have no life but not in this situation. ;-)

Good luck!
