About a decade ago I was out drinking and met this bartender and her girlfriend, who were out bar hopping. She invited me to come visit the restaurant she worked at and when she would be working next. I showed up at her next shift and she treated me really well. So well that when I was calculating the tip I doubled it twice and left a 40% tip accidentally on a tab that was probably in the $150-$200 range. The next morning I saw the receipt and chalked it up to good karma.
On my second visit everyone that worked there knew my name (and said hi) and both owners came out to my table to say hi and ask how the meal was.
Over the years I continued to get the personal treatment, was invited to private events at the restaurant and eventually was invited to private parties of some of the employees that I got to know better.
All In all a very well spent ~$80.
