There is a whole category of jobs devoted to wedding ceremonies in my country (Uzbekistan). I don't think they exist in other cultures. Let me tell you some of them:

-Pilaf Logistician: I could not translate it any better to English. This is the most respected job in the wedding, as it involves fast decision making, accurate estimation and exceptional organization skills. It is customary to Uzbek culture to cook 200-300kgs of pilaf in the morning of the wedding day and give it out to more than 2000-3000 invited/accompanied by guests. The guests are exclusively male (sounds a bit sexist), and according to tradition younger guests first serve elder guests, and then serve themselves. This quite dynamic event. The Pilaf logisticians job is to recruit waiters out from newly arrived youngsters, organise them into well structured distribution line (literally it is a line of people handing over pilaf to its main destination), seat batches of guests as they come in, estimate how much pilaf is needed as the guests come, operate the transmission of pilaf over distribution line to the destination table and backwards to the kitchen after it is eaten, check for the availibility of hot tea after pilaf, and finally give quick blessings and thank guests for coming.

• Head Tea-man: While pilaf logistician is minding his own business in building his distribution network out of new recruits, head tea-man has to organise his ow network for distributing tea in the wedding hall. Due to the specifics of the logistics of tea, they cannot be handed over through a giant line of people, and has to be delivered by ping-pongers who take empty pots to tea-man, who by smell only identifies which tea it had before, and refills it with exactly the same tea in the matter of 2-5 seconds. Also the job of tea-man is to collect initial preferences on tea from guests and make them delivered.
