Round numbers indicate inaccurate accounting: Snack and meals: 800, 1200, 1600, 1800, 650, 1400 and 8500. GASOLINE: 1500, 1000 and 500. Even I keep receipts of my gasoline expenses, it doesn't make sense to spend 2+ Bitcoin of donated funds without keeping a single receipt.
This is why I mentioned they need to break down the exact cost of every item they bought for audit purposes. We will never get anything down to the penny regardless, but I do not think it's too much to ask that some effort be put into accounting by these guys.
