Got too nervous to call out the bitch who cut in front of me at the gym

Got too nervous to call out the bitch who cut in front of me at the gym I was waiting forever for a piece of equipment, and the asshole using it didn't unrack his plates before just walking away. Normally I'd walk right in, but I hesitated because I wasn't sure if he was actually done or not. During that hesitation, some woman walks in and starts preparing the bar. I try to muster up the courage to tell her I was waiting, but as you've guessed by now I got too nervous and said nothing. Now I feel like a weak pathetic piece of shit. Fuck this fucking curse.
