Saw this recently in a foodcourt.
A family of 5 sat down at a table. Daughter in her early 20s or late teens (not chio), middle aged parents, grandparents probably in their
70s. Daughter was fiddling with her phone, mother was talking to grandparents. Father took everyone's "order", went to the first stall, ordered, waited, and carried the food back. Repeated the steps at the same stall, then went to other stalls to repeat the same thing, until everyone including himself was served.
Can understand him serving his parents or parents-in-law, since they are elderly. Cannot understand why the wife (who looked perfectly healthy and well) and the daughter could not buy and carry their own food.
Perhaps the man was being a filial son, loving husband and supportive father.
My view is that there are some things u would expect the father or the "man of the house" to do for his family members, but being a waiter in a foodcourt to his whole family is not one of them.
