This sign is on the Gala Shop on Camden Quay. I spotted it last week.
Since then I have learnt that I was wrong – not the sign.
I would have thought that ‘til was the accepted shortening of the word ‘until’ but Chambers do not agree. Collins are on my side though.
Chambers confirmed that ‘till’ is correct and similar to ‘until’.
I do not think I will be using ‘till’ but good to know.
