Pfand

　　I had reserved the Sheraton Hotel at Frankfurt Airport for the previous night of my departure. This hotel was very convenient and I used it again. I checked into the hotel at 3 o'clock and went out for a walk in the airport. The renovations were still underway. I bought some beers and drinks at a stall in the airport and got them back to my hotel, because such items were usually a higher price in the hotel. On that night, I found the word "Pfand" on my receipt as I am showing you in the picture. Pfand means the guarantee money and I took the empty bottles back to the same stall the next morning and successfully got payed back a small amount of money. This would be the German or European way of recycling. I wondered if they would do the same thing without any refund.
