I believe that where I live the license plate numbers would also not be considered personal information. This might work here too, if a different exemption was not claimed, although I'm not aware of anyone using this technology near me.
The server must have to send some metadata to the client telling when it's running an ad because there are other things that need to happen client side during that like adjusting of the time or making the ad clickable
True, and they do use normal surveillance cameras too. Personally I am interested in facial recognition systems as I've seen the back-end of facial recognition systems in other retailers and it was incredibly creepy. They may not actually be keeping track of card #s the same way other stores do*, the biggest red flag in the statement to me is it doesn't rule out more general demographics tracking tech, which is something I don't think is covered by the legislation. There may be a little bit of a language barrier in this exchange as well. But I think most people aren't very aware of even what privacy laws exist, compared to eg. the GDPR which is quite common to hear about online.
*(I want to try something similar for Mark's since they can be seen tracking card #s in a very overt way.)
The comic subverts our expectations when we expect that "it's complicated" is just an easy way to brush off the question only to find out that the answer is in fact, complicated.
The juxtaposition of a normal social situation with the absurdity of the mouse hospital pizza parlor serves to further build the humour in this comic.
So glad I paid $300 to take that humour theory class in college.
