Berkhamsted town councillors think letting Domino’s sell pizzas later into the night could cause more litter and bad behaviour nearby.
But at a meeting on Monday, they said there was no planning reason to object to the proposals for its Berkhamsted High Street branch.
The firm wants to extend the opening times there from 11pm to midnight on Sunday to Thursday and from 11.30pm to 1am on Friday and Saturday.
Councillor Tom Ritchie said: “The litter that comes from these pizza boxes is huge. I think we are just encouraging additional litter in a part of the High Street where we do not at the moment have this issue.”
He said there could be more anti-social behaviour as nearby streets will be ‘completely dark’ at closing time.
Meeting chairman Laurence Handy said nobody has objected to the plans, but councillors recommended the firm hires to prevent bad behaviour late at night.
