An interesting piece as quoted from Investopedia:
Hot Waitress Economic Index What Does it Mean?
An index that indicates the state of the economy by measuring the number of attractive people working as waiters/waitresses. According to the hot waitress index, the higher the number of good looking servers, the weaker the current state of the economy. It is assumed that attractive individuals do not tend to have trouble finding high-paying jobs during good economics times. During poor economic times, these jobs will be more difficult to find and therefore more attractive people will be forced to work in lower paying jobs such as being waiters/waitresses.
