I argued a similar point at a sporting goods store once. Their clearance prices were 50% off. They came over the loudspeaker and said that for the next half hour, all clearance items were 75% off. So I bought something. When the clerk rang it up, she took 50% off. Then she took 25% off of that total. I explained three times that she was wrong.
If you take 75% off of $100, it's $25
If you take 50% off of $100, it's $50. If you then take 25% off of that, it's $37.50
She finally had to get a manager to ring it up properly.
The way this was stated ("clearance items 75% off") was straightforward and correct.
OTOH, if the offer had been stated as "an additional 25% off," the uncertainty comes from not specifying whether the additional discount is off of the starting price or the effective price after the first discount has been applied.
