Stewarding on the whole is a volunteer basis, where you pay a deposit for your ticket, and then do the stated amount of shifts to cover the cost of that over the weekend, and then get the deposit back after the festival/season depending who you work for. Bar staff is a mix of volunteer and paid work, similar to above if volunteering or if paid then you dont usually pay a deposit. Volunteers tend to do less hours over the weekend, sometimes can be 3 x 6 hour shifts, but varies depending
