So I really need advice. Im 18 and a part time waitress in a restaurant and worked last night. I was dealing with a party of 20, they were all men. Throughout the whole night they were ok ( some were a bit rude and kept asking where their food was ) anyway they were finally leaving. & as I was cashing up on the till, they all walked behind me to leave, all saying thank you. Then all of a sudden I feel one of the men’s Crotch on my ass, as if he was pretending to grind, but I actually felt his crotch on me... i just kinda froze, and tried not to get upset. I never told anyone as I thought I was being over dramatic. Has anyone got any advice for me ?
