I worked at Wendy's....about 33 years ago. The burgers were advertised as "hot & juicy" and we were trained to take them off the grill right when the pink was gone but before they got all dried out.
In recent PC years, they quietly dropped the "hot & juicy" advertising slogan and cooked them longer.....I guess to appear more health-conscious.
They recently resurrected the old "hot & juicy" slogan. I had one last week and I can say it was just like we used to do them 30+ years ago. They're also using Wendy Thomas in the commercial. Maybe she inherited a leadership role and is going to shake things up?
FYI: if the person running the grill gets too much meat on the grill and over-cooks them, they get sent to make chili. That's their method for enabling all burgers to be made fresh off the grill instead of sitting around.
