I don't tip more than a few dollars unless the server did something well or was especially nice. Seems like many servers these days just expect the 20% bonus just for taking an order and carrying food around, regardless of attitude
Reminds me of The Octopus episode of the Swindled podcast. I wouldn't be surprised if it eventually came out that pesticides/herbicides/etc are the cause.
I think the local guide system google set up is the only reason I bother to read Google reviews. It's nice to have the guarantee of "here's a review by what is probably a real person who lives near this business and reviewed this out of kindness/boredom"
Have you tried paying higher than the market rate ( like what you would pay a travelling nurse/CNA) instead of signing bonuses? CNAs make less than amazon warehouse workers in my area. If I'm a nurse, it's only natural I'm going to seek a less demanding patient population asap unless there is a significant incentive not to do that, especially given that every hospital in the country is hiring nurses at all times.
