The Walking Dead
Okay, so zombies from the television show ‘The Walking Dead’ didn’t really enter a restaurant and started behaving poorly. This person is referencing the director and other members of the show who ate there regularly. Apparently, they always left good tips and were looking out for the staff whenever they could.
We would expect nothing less from the owners of the place, who want to make sure that they are keeping their workers happy. Remember, if you do not pay your employees then you risk them turning on you, just like in the zombie show. We think that the director was well aware of this.
