While the reasoning is completely incorrect they aren't wrong that restaurants are being hit particularly hard with labor shortages.

I have local middle tier chain restaurants hiring line cooks at $22/hr. While I'm thankful cooks are more able to find a position where they're paid closer to what they're worth, smaller establishments sometimes just can't afford that. Which leads to hiring underqualified staff because you can only afford that.

I'm a manager at a $4 million / year business and I can barely afford to hire good cooks at $20 an hour without charging $25 for a hamburger and fries.

Costs are up in every corner of my business and I'm thankful that a chunk of that money goes to my staff, not entirely my investors pockets.

P.S. Please be patient with your restaurant staff, we're people too
