Next blip, please.

Daily at 5p.m, UK viewers would watch a live TV briefing giving the latest covid statistics and government advice. A slide projector would be used, and 'next slide please' became a catchphrase. However, it didn't create a demand for slide film. 
Whilst I was taking this, outside a recycling shop window, a passer by asked me where he could buy slide film. He presumably thought I looked non digital. We then had a chat about old Russian cameras that he owned (My first camera was a Zorki 4k, built like a brick and with a lace thin shoulder strap that used to dig in.)
