I attended an all girls school, & we were taught how to get undressed/dressed in the non-cubicled(in those days) dressing shed at the pool.
When the new pool was built, we had cubicles. I swam thrice daily, & usually had a cubicle to myself. What luxury!
BUT as Senior, & Open Swimming School Champion, & School & Inter-School Swimming Captain, for two years in a row, & Lifesaving Senior, I DID have some priority!
Oh! The 'perk' of swimming constantly, bringing Honours to my school paid off! Yay!
