So you are at the barber/salon for a service. You frequent the establishment every 4-6 weeks. Before your appointment you use the restroom. As you enter you don't notice anything in particular, but as you are washing your hands you notice cash on the floor. It's folded neatly. it's 5-7 twenties, a couple of tens fives and a few ones. You think it must have fallen out of your pockets/bag. You had recently gone to dinner with friends and used your CC, and they gave you cash that you still had. You put it in your wallet, and go sit for your appointment. About 20/30 minutes later you notice an employee walking around the shop looking for something, they are checking their pockets and clearly looking for something they had lost. What do you do?
