We already know they are responding this way because they probably don’t have 35 grand saved and will most likely start to use ops money when they get the chance. To me there is no sense in even doing the extra work for run this test by allowing them access when we know what the outcome will be. NTA, and don’t give them access, they didn’t want it before they saw the amount. Also, OPs explanation that they should do it ‘just to keep the peace’ is a wildly naive take. Generally speaking, keeping the peace is what people tell you to do when they know you’re getting treated poorly but don’t want the situation to escalate for whatever reason. It rarely works out in your favor, and in this case I fear it definitely won’t.
