Rude staff at Nigel Licensing department

To renew your driver's license card, you need to make a booking online and gets allocated a specific timeslot. I arrived at the Licensing Department and was told to stand in the queue. No respect was paid to the fact that an online booking with an allocated timeslot was made. That was the easy part. When I got to the cashier, the guy was not wearing his mask, he was extremely unprofessional and asked for my Bank card together with my ID and license card. Since when is anyone expected to hand over their Bank card to a cashier behind a counter and a glass window to perform payment, while there are card facility devices on the customer side of the counter? The way customers are treated, is appalling and the staff are rude to say the least.
