daddy...why do they sell condoms in a hospital?

Was what i asked my dad in the hospital shop today on spotting them. Why??? They don't sell things like cigarettes (which i think they should since people who smoke and are in hospital can't exactly hop out to a shop...yes its bad for you to smoke but hospitals are often stressful enough without smokers having to go without. Besides they sell plenty junk food!)

Anyway my dads response was, I've found something more worrying...and pointed to these wee guides. Lol.
