I speak as an ex employee of Southwark Libraries btw.
Went to print off a document, had to join (Grove Vale) the sign up process was a QR code! My pet hate when used in restaurants etc.
We talked about my printing needs, apparently I could have printed from my phone! (email)
A customer was enquiring about a book, they quickly established no copies available for loan - but checked whether an audio copy was available!
I know I probably sound 100 years old but I am online and on the mobile frequently. Lots more than some contemporaries.
Positive vibes all round, pleasantly surprised
