A problem at my gym. what can i do about this. please help.?

so i started a gym a a week ago. and everyone and the staff seem really nice people. but so 2 days ago i went early at 8am. so i walked in the gym and one guy that was in the front desk that scan ed my card. and he said it doesn't look like you. and he said let me take you another picture. and im like oh its maybe because im wearing make up. and he is like who wears makeup to the gym. and im like well i went to to a party last night. and he is like ewwww so you did int take a shower that's nasty. he said that in front of alot of people so i got embarrassed. and i told him well why would i shower before going to the gym. i got really pissed. then when i was going out after my workout he yelled take a shower next time. i told him asshole and left. ughhh i was so angry. then i went yesterday to the gym again and saw him again and he is like so did you shower today. i didnt say anything just look at him bad. its getting annoying. funny thing is that he is trying to flirt. i cant stand him. can i report him to the office. what can i do. or do you think it something dumb to report. because i dont want to go in every morning and him telling me stuff. what should i do?
