In the past, plates and cups were not provided for any visitors in Bhutan. Everywhere people must travel with their own plates and cups as this is part of traditional etiquette. Usually, people bring at least two Phob (traditional wooden cups) and a To-rey (a piece of cloth) instead of a plate. The size of the To-rey must be kha-gang, which means slightly more than half a meter and slightly less than a meter, which is equivalent to a two-foot square. This size and quality of the To-rey applies to every person, regardless of status. The Phob wrapped in the To-rey is carried everywhere in the Hem-chung (Gho-pocket or hanging bag) of our Gho and Kira (traditional Bhutanese clothing). The cups come in a variety of shapes and varieties and are made of different types of grains. There are cups with silver and gold layers on the rim and inside the cups, or plain wooden cups that signify the different status of the people depending on the quality of the cup used. There are certain cups that may only be used by monks and lamas (Buddhist spiritual leaders). This is usually the La-phob (monk's cup), which does not have exquisite decorations like the Phob of common people. However, the La-phob has historically used different colors to denote different monastic titles. On formal occasions, when we sit with our legs crossed or in meditation posture, the To-rey must be able to cover the surface of our leg. It was not until the turn of the 20th century that people began to keep extra plates and cups for guests, as there had been no development until then and the country and its citizens were economically backward. This happened only when people began to import tableware into the country from abroad. Until then, people used phob (wooden cups), Dha-pa (wooden plates) and Bang-chung (hand-woven bamboo plates). Each household member owned a Dhapa or Bang-chung, at least two Phobs, and a To-rey, which served as a shawl and a cleaning cloth for the plates and cups. The plates and cups were wiped with the To-rey, which was cleaned after a few days, as there was no tradition of washing the utensils.
