The employee took the devices, issued discounts, but forty minutes later refused to glue the films, citing problems with the equipment. I suggested leaving the devices at the point overnight until tomorrow, otherwise the discounts will burn out (an absurd offer).
He did not provide a paper envelope for the tablet, offered to carry it home without a cover in his hands so that the film would not move, which he did not warn about at first.
Forty minutes wasted. It is easier and cheaper to stick films next to the point of sale of covers than to deal with such a service.
