Haha babymilly! Dont panic, people very rarely tried pants on as most people assumed you couldn't. Id say for every 1000 pairs of pants sold only one had been tried on. Same for returns, when on service desk I think I maybe only returned about 5 pairs.
The people that tried them on/returned them did get talked about by staff after. Having to put them back on the hangers was the worst part, yak!
