How Much Work is Involved in Getting Bread and Milk for Julia? (Ep. 6)
In episode 6, Julia rings for Wilcox late at night. No doubt asleep, he had to wake up, put on his tuxedo (he can't be seen without it) and rush to answer the call.
Julia tells him "Wilcox, I'm starving! Is there any bread and milk?"
As Wilcox does not work in the kitchen, he would have had to quickly wake up the cook, who probably then woke up one of her underlings to go into the kitchen to get bread and milk for Julia, who then gives it to Wilcox who delivers it to Julia.
No doubt Wilcox would have to retrieve the dirty dishes in the middle of the night when she was done, bring them into the kitchen where a kitchen staff member would wash them.
And all because Julia doesn't know where the kitchen is located in her own home, and would have no idea how to find bread and milk even if she did.
"And take that filthy dog out of here!"
