This short voice clip lasts about six and a half seconds and catches a speaker switching from a surprised 'ah no' to a firm, repeated 'bueno no', the Spanish phrase for 'well, no'. The rushed delivery makes it feel flustered and funny, like someone backtracking in real time after realising a plan has gone wrong.
