I for got to mention why the $25 seemed important.
We try to work with what the organizer normally does. For us its more important to perform every night on tour. So on a couple of occasions we agreed to perform for meals, rooms and donations. (Beats a motel and meals in US $$).
At one we found as we were driving down the road that neither of us had picked what we knew were scanty donations. (I thought you did!) So, we e-mailed the organizer the next day to check. He said they were so minimal he was embarrassed to give us half. (We were expecting all the donations.) So, instead of giving us the whole door he kept the whole door. Life on the road. The difference is the one we will go back to the latter we won't.
