It’s dumb. It’s like when Disney tried to trademark “Day of the Dead” and except the trademark people were like “No, Disney. It’s already a thing, you can’t keep it.”
I reckon “Should’ve” has been used in slogans before, like “should’ve bought x-brand!”, goddam it specsavers. I used to think that you were a fine company with varying and humourous adverts in a world of terrible adverts and you go and do something unecessary and douchey and just fucking wrong. Ugh, you’ve gone way down in my estimations you goddam idiots. Also special fuck you to the wallies that authorised it.
