In the first instance, yes.
I would expect that the park should have appropriate presentation stipulations in their work contracts.
I would also expect that relevant park staff would check and confirm this was done according to those presentation standards each day before opening. its a minor attention to detail, and its a couple minutes to fix if its fresh.
And before anyone jumps in that this isn't disney or they don't have the time to spend running around after tradespeople, etc - Wonderland, supervisors would walk the park prior to gates open. On at least two occasions I can recall gates being held because a contractor vehicle was still on stage. Particular attention was paid to any areas that had specifically had work done overnight to make sure doors were shut\locked, no hazards were present and everything was looking as it should.
