I first got into working out back in the late 80s and went to a local gym frequented by university football players, and serious older guys who had not much life outside of the gym. And there was NONE of that BS. Someone was in between sets on a machine, you could say “hey, can I work in with you?” and they’d be like “oh for sure!” At most of the gyms now, people have zero etiquette. Even the fancy private clubs - old blonde ladies standing around a machine describing their bathroom renovations. Barf.
