The UK's biggest toy chain has warned that children's presents might not arrive in time for Christmas if shops are shut through December.
Mr Grant said The Entertainer had seen one of its strongest ever Octobers last month as consumers moved their shopping forward due to the pandemic.
He said the company was prepared for the second lockdown, with click and collect services in place at stores and an investment into expanding its online capacity.
But he stressed that it would still be vital that some stores open next month to ensure that retailers such as his can meet the spike in demand they typically see before Christmas.
He warned that there just wouldn't be enough couriers to deliver the gifts in time.
He said: "Last year, we were delivering at 100% capacity in the run up to Christmas so it's hard to even contemplate what will happen if stores stay shut.
"In that case, we won't be able to deliver all presents in time because there just aren't enough white vans for all retailers to deliver these goods to homes."

The British Retail Consortium is among groups calling on people to start their Christmas shopping early amid concerns that closures this month could lead to a challenging December.
The chain was among non-essential retailers to close their doors from March until June as a result of the first lockdown period.
