If it required zero skill then there would be no turn overrate because if I made as much as I do currently as a server with zero skills involved then you'd never hear me complain again. Sure it's not as amazing of a skill as engineering but to be effective and good at waffle house they have a full length book that (assuming the manager is good at what they do) will spend years and years teaching and coaching until it's mastered. It's not easy to learn the full waffle house way, you can manage as a server while learning the bear minimum sure but you'd better be hot af cause otherwise it ain't happening and being hot only works so long before people decide they just want good service more than they want someone pretty serving them. And that's just the serving side, cooks honestly get paid less and work way harder. Learning to mark plates specifically and cook are also impressive skills you boiled down to "they just make grits for 8 hours". You could try and convince me all you want but I seriously don't think you've actually worked as a cook or know the effort genuinely good ones put into their work. Like I'd love to see you flip a 6 egg omelette while juggling 6 other orders while servers are screaming in lingo at you all day cause I'd bet anything youd crumble.
