Cafe Prague in Morrison Colorado reuses the complimentary butter from tables. When I worked there part of my job as dishwasher was to collect the butter, so that they could use it as butter on the cooking line. They felt that since it was used to cook with it kills everything. This is, of course, not true. This was during the pandemic too. When I called the health department they called the restaraunt and told them they had a “snitch”. The owners then went around the restaraunt promising to root out any “communists”.
This was some time ago, and I have no proof but my word, but its the truth, and I thought this sub would enjoy the story.
