Do you remember when chemist's really were chemist's, not just a retailing chain with a sideline in medicines?
Our local Boots are dumbfounded by enquiries for pectolase (OK maybe that's a bit obscure) and potassium carbonate. It's not like "Oh sorry not enough demand to make it worth stocking", it's more "Don't even know what you're talking about".
Antibiotics still worked in the late 50s and early 60s, too.
I feel old.
