My old college dorm did this, I told them I don't have a smartphone (lie) and they gave me an access card that works 100% of the time without needing a charge. They might do the same at your gym.
I used to work in a fish market that processed wild caught fish fresh every day. Nearly every single fish we cut had some worms in it. Cod was the worst, salmon was middle of the road, flat fish like flounder seemed to be the least wormy but still had it. Maybe they were just harder to spot idk.
