The store says feedback from customers was negative after they removed some manned tills.
Chris Graham, Morrisons Gamston Store Manager, said:
“Our customers in Gamston told us that they were not happy with the changes we had made to our tills.
“We have listened to this feedback and have invested in more pairs of hands at checkouts to speed up the shopping journey for our customers in December.
“The store will also open all of its main bank tills for full trade on the 22nd, 23rd and 24th December, during peak trading hours.
