Well, you have to remember that the housekeepers and maids are people too, and sometimes if they have a bad day, any little thing can make them cry.
My aunt had a maid who missed her son and it happened that my cousin at the time was about the same age as her son - so each time he came in the room, she'd burst into tears. Obviously this was not going to work.
My grandmother's maid has a tanty every few years - so the family gives her a pay rise and suggests she take a break - this woman never takes holidays! But she gets over it.
But the one that takes the cake - we used to have a cleaner who comes in each week, and she did a great job, until one day, I was at home sick, and she was vacuuming downstairs, then I went downstairs to get a drink, and walked into the kitchen to see her drinking orange juice straight from the carton!!!

Don't mind that you need a drink, you can drink whatever you like in the house, but I would like to see some hygiene! Even though it's my own house, and my own orange juice, I never drink it straight from the carton!
