Disappointed at the treatment

On Friday the 7th of July 2023 at Planet fitness in Parklands, I had lights switched off on me while I was taking the shower. I had not realized the gym was closing that was my fault I acknowledge that. The worst part is how the guy who switched the lights off, saw me going into the changing rooms but did not say to me that they are closing its 8pm already nor did he come back to check if I had left the bathroom before switching the lights off. His reply to me when I asked why he switched the lights off on me, he said he thought I had already left. I dont know how he would have missed me leaving the gym yet he is near the exit. He proceeded to tell me that I had no reason to be scared when I told him I thought I was locked in the gym, his reply was " Scared for the lights being switched off, its not like I locked you in". I was so freaked out by the experience and asked how come they dont alert people that they are closing, his collogue asked me did I not see the sign on the door, how long have I been the member of the gym. At no point was an apology offered to me, not sure if that was because I am Black. Nico if that is even his real name as he was not wearing a name badge, told me that I am wasting their time he needs to close, can I leave the establishment and he hopes I have a lovely day further. I walked out and told him to f*ck off and he rep**** f*ck you too. We leave in a country where women get hurt everyday in well established places and now imagine how I felt to have 2 gentlemen left with me alone in the gym and then secondly having them switch off the lights on me while I am naked? At no point did I realize that the gym is closing, if a gym is closing does it not say to people in the gym to please wrap up as the place is closing? I mean that way for people like me who are not paying attention to the time or who were at the gym in evening for their first time in their lives can be aware of the place closing. I am soooo disappointed how I was made to feel little when I expressed how the situation could have been handle. I am also disappointed at Nico for telling me not to shout after he was the one who saw me entering the changing room and yet it was still him switching the lights off on me while I was showering.
