How do people celebrate their MACH/PACH?

I'm wondering how different regions celebrate a person's MACH/PACH, specifically MACH/PACH parties. In my area at a trial after the MACH is earned, the person's friends will have a party for them. Also, on the run they earn the title they grab the last jump pole and run around for about 20 seconds and get pictures with the judge after the trial. At a later trial the party consists of a full buffet of food, cake, and some other desserts usually. Anyone at the trial can join in. This is affecting our ability to get food trucks to our trials as fewer people go to the food truck when free food is available. The food truck is our only on-site food option. So I'm wondering how other regions celebrate a person's MACH/PACH?
