Check the claim against the source

Here is a fictional event listing:

"Repair café. Saturday, 14:00 to 16:00. Library hall. Bring one item. Booking required. Booking address to be announced."

A prepared draft says:

"Drop in any time on Saturday. Repairs are guaranteed."

Treat the listing as the organiser's confirmed information for this exercise.

Check three things: does the source exist, does it support this claim, and does it apply to this event?

Which parts of the draft conflict with the listing or go beyond it? What would you change?
