I was watching Suzanne's 250k I think that it was mainly due to dismal game play from The Banker I think he still had a chance of an OBW at 5 box but that 30k offer was so dismal and by the time he realised the error it was too late and he was just bracing himself for the impact due to Suzanne being tunnel vision on the confetti what do you think

Keep in mind the "Banker" in reality is just a person representing the production team, who makes offers with the goal of making the best tv product. After Wilf and Michael copped out of golden boards for insanely low offers earlier in the week, they wanted to make Suzanne's offers low enough that she wasn't likely to follow suit. Then once that last blue went and life changing money was guaranteed regardless, there was really no point in going really low anymore, hence the sudden hike to more reasonable offers at that point.
