advice

so i am a 21 year old young woman. about two weeks ago i went out to eat with my aunt who is more like my sister (only 5 years older). i was wearing a romper with a long flowy skirt attached...perfect for the summer weather. we ask for a table for two and then our waiter walks up and he’s about mid-50’s to 60’s and the first thing that came out if his mouth was “everyone is talking about your dress its so beautiful!” in which i smiled and said thank you then started to try and order a drink. he cut me off and immediately said “but i don’t care about that dress your body is amazing too” and winked...it never stopped. the entire time i was there he kept talking about it. another male waiter came to simply refill our drinks and this man came and snapped at him and said he only wanted to come to the table for “the pretty girl in the dress” and kept directing the attention towards me and my body. i felt like i wanted to cry. i felt so vulnerable and exposed. i wanted to literally disappear. my aunt was horrified. i trued to just ignore his comments...i didn’t know what to do! when it was time to leave i was scared to stand. i waited until he walked around the corner to get up and quickly leave but as soon as he saw me stand up he raced over to watch us leave...my aunt had to stand behind me just to somewhat give me some respect. my heart was racing i felt so uncomfortable and sick at my stomach. to me this was sexual harassment...i’ve hesitated calling the restaurant because i’m scared and honestly i don’t even know what to say but no one should walk into a restaurant to eat and be made to feel like they are being preyed on...especially a young woman. please help. i need advice. i still feel disgusting since that day.
