I'm in the UE and I get an extra cookie banner (with a design not matching the website's) on top of the "standard" one. This extra banner has a "Reject all cookie" clearly visible and clickable.
It showed me the reject all on top of the accept all. Clicking reject all left me looking at the accept all banner. Only options were "accept all" or bounce.
This doesn't speak highly of their frontend team with the "I am very smart" undertone other comments mentioned.
