Was one of those... reinforcing the floor for dropping weights?
My gym is on the 1st floor with commercial offices below. BANG! when the 10 kg weights are dropped.
We have retail shops and food outlets below our offices that keep on setting of the fire alarm, like earlier today. Mass evacuation!
As in leaving the building, or a sudden fearful rush for the loos?
Too bad we can't cut you loose.
If you did you'd be flushed with success.
