I realize all of that - and yes, it’s a high likelihood of being BS. Doesn’t change my point to the poster who assumed she was down on her luck - which is that wait and bar staff in such establishments make good money. Those jobs are coveted. Those who have them are not down on their luck.
Now, if they’re at the Waffle House - that’s another story.
I’ve dated Waffle House waitresses in the past. They make more money than you think. As to high-end (or even mid-level) steakhouses. I made so much in tips as a part-time bartender at a “Steakhouse and Saloon” type business near a capitol city airport (I also got 20% of the waitresses tips) that I almost never cashed my hourly checks, even though my hourly pay was over $6/hr. and just let them accumulate.
When I am dining alone at the Waffle House, I just double the check. Those waitresses work hard, and it's still cheap.
