Bikini Contest - bad experience/different?

Last night i was at a night club and entered bikini contest for the 1st time. What I came to find out was it was a skinniest girl bikini contest. What that meant is they had a digital scale on stage and one by one we got weighed in infront of everyone and they showed our feet on the scale up on a big screen so EVERYONE could see our actual weight on stage. I was totally in shock. They gave out cash prizes to the skinniest girls in different height ranges. 5'3 and under $100, 5'4"-5'6" $100, 5'7 and up $100. Everyone was so skinny it was crazy. I thought i had a chance until started to see the trend of what other girls were weighing in. Im short 5'0 and weighed 121. The lowest weights that won for the heights were as follows. A girl won at 5'0 87lbs, 5'5 96.2 lbs, and 5'7 102.7 lbs. I was shocked at how thin and that the crowd was into this sorta competition. I couldnt wait to get off that scale. Of course the girls that won got back on the scale again 1 last time as the rest of us stood in shock at just how low their weights were. Surprisinly they didnt look that sickly. The girl who was 5'7 you could see all her ribs on both sides when she was sucking in which yes was VERY worrisom. Im still in shock that i competed in this and that they actually had a skinniest weigh in contest for girls 18+. Apparently since it was a big hit they will be having them again. Not sure if i will enter unless i lose some weight. Anyone ever experienced anything like this even if it was at a house where girls were weighing themselves to see whos weight was the lowest? I highly doubt u saw a contest at club like this but if anyone has experiences similar please share what you saw or heard about. Not saying the contest wasnt fun, its just threw me off and was totally different than all other club contest.
