In order to keep high position on the premium hotels chains and provide good quality service for customers, Hilton hotel has a several suppliers in each city where its have a Hilton’s branch. The most important areas that hotel pays its attention are food, drink, interior design and motor service. For example, in food department, once the goods are delivered, catering department must store them in the right time and in the right temperature in order to save quality of goods. Hilton has a very unique technique of caring the goods, for example, catering department uses color stickers
which reminds them about good’s lifetime and its deadline. If it arrives on Sunday or on any other days and good has five days of lifetime, the color sticker with the word “Thur" must be put on the package to inform the staff that it must be used by Thursday or otherwise it will be binned to avoid poisoning. The same practice is also related to other hotel’s
services
