I have come across the following sentence in Activate Level A2 by Carolyn Barraclough, Elaine Boyd, Suzanne Gaynor, Megan Roderick, Mary Stephens:
The only bad thing was that it was very busy so we didn't get time on everything and it is quite expensive.
I have found out that you can 'have/find/make time for everything/tennis/long walks'. My question is whether it is grammatically correct to use preposition 'on' here. Any reliable sources are appreciated.
