When you run a dining room in a hotel , motel etc you need to provide adequate training so that employee's or owners that serve in the dining room know exactly what they should be doing.
I recently stayed in a motel which had a dining room that seated about 30.
Well run dining rooms know the table layout & the number of diners on each table.
When taking the orders the employee's will record where each diner is sitting so that meals can go to the correct diner.
Therefore it was interesting to see meals coming out of the kitchen and the waitresses then calling out a name " Mary " and waiting for Mary to acknowledge that was her meal.Then " Bill" was called and Bill put his hand up to get meal.This went on all the while I was there.
It was an interesting experience and quiet entertaining but not a great example of customer service.
