We had to operate on trust when we did it … people brought for others on own cards and used other people’s cards some used prepayed cards . But we had a longer period of getting to know people over pandemic . There will be option to cancel payments with banks if you aren’t payed back I think . But if you don’t do this the risk of not getting tickets is much higher … the whole idea behind groups is that everyone works for everyone untill you are 100% complete or you might as well not bother grouping up .
