Overcharging bills

They overcharge a bill, we drank a certain amount of drinks and when the bill came they had put more drinks than what we had. We went to the manager and they showed us cctv footage of us drinking and as expected, the extra “drinks” were not shown on the cctv, they insisted that us (two women) go to a random room with the two men to see the rest of the footage. Obviously, for our own safety we refused, and we’re bul**** into paying the bill with the extra drinks not shown on original cctv. Not the first bad experience, would not recommend
