He paid in quarters
As a server, most of his cash was from the tips he earned. These came in the form of small change that people left on their tables – often quarters. And after some time, Cohen was able to have a neat pile of coins. He had enough to pay for the meal and leave a nice tip.

Cohen and his friends had a great time hanging out and eating their lunch together. When it was time to pay the bill, he paid the waitress using the quarters that he had saved up. As you could imagine, it was a lot of coins.
They posted about it
Later, Cohen was surprised to find that Beer 88 made a post about it on their Facebook page. The post was written by a waitress who was complaining about having to deal with so many coins. Along with the post came a photo of his bill and all the quarters that he used to pay for it.

Although no names were not mentioned, Cohen could not help but feel embarrassed. After all, he brought his friends along and if one of them sees that post, he is pretty sure that he could easily be identified.
