I don't think you were quite grasping the scope the McDonald's operates at. That's only a couple hundred per location, and fast food restaurants tend to have extremely high turnover, so that's definitely not an unrealistic number.

ETA? Estimated Time of Arrival?

One of us doesn't know what that stands for. I feel like the time my grandpa died, and mom sent me an email telling me "We're going to the funeral this Friday to pay respects to grandpa. LOL!"

I was quite confused. Turns out she grew up with "Lots Of Love". For a second she seemed like she turned into an absolute psychopath, for like....no reason.

They have over 40k locations. Many are 24/7. They also surely churn through employees, have many part time employees, and probably get many more applicants than they hire.

The employees will be hired by the franchisees but they still use the McDonalds software.

Millions is not a surprise to me at all. Perhaps that it's tens of millions is a little surprising, but it still seems within the realm of possibility.

i mean there's a shit ton of unskilled labor out there whose vertical reach isn't that great.

They pay well everywhere but the US.
