Anyway, I went out and told the staff, who were extremely interested, as you might imagine, but I got the impression that nobody wanted the job of going in there and telling those women to stop. I returned to the change room and spent the next ten minutes getting changed. The staff member who drew the short straw would have had to walk right past me to get to the showers. Nobody did. I guess they thought that if they just waited a while, the situation would resolve itself eventually. Since the two women got away with it, they might try doing that again in the future, whereupon some Mom is going to yell at them and ruin their mood.
Maybe it's the new machines with the TVs on them, but my gym has definitely gotten more interesting lately!
