Probably true.
My daughter (one of them), worked in a Louisiana Waffle House while my son in.law was in the Air Force there.
I love Waffle House food. Staff are nice too.
I read they sell a LOT of their Tbone steaks as a chain. Big numbers. Reasonable prices.
Love their hashbrowns with “everything”.
I go to my local Waffle House a couple of times a month. But not after midnight.
